Research dump van soc’s en MPU,s
Het is info uit wel 100 verschillende forumposts en spec pagina`s. Alleen al alle atmegas en hun Specs bij elkaar vinden was een week rondzoemen, maar ja, das mijn vorm van ontspanning als ik in bed lig en t lijkt een beetje op schatgravertje spelen. Vooral als je plots een super low spec mpu vind waar je echt nog nooit van gehoord hebt en dan op YouTube filmpjes ziet dat er iemand dan toch nog een game op aan de praat heeft gekregen zoals de attiny 13 a die maar 64 bytes aan ram heeft. ( bytes, NIET Kilobytes dus]
Dat geld ook voor die ouderwetse handheld lcd games zoals de game en watch met donkey kong.
Wist je dat daar de zelfde 4 bits processor in wordt gebruikt die eigenlijk voor rekenmachines is bedoeld? En dan wordt er eigenlijk niets berekend, het zijn puur looplichen met detection als ze elkaar teglijk kruisen.
Dit is dus mijn research wat ik doe voor ik aan een blog begin,
Het is soms een hele puzzel om alle Specs en type van een processor bij elkaar te vinden.
Ook zitten er verschillende commentaren en stukken interviews tussen. Zie het maar als een grabbelbak. Het kan wat wanordelijk over komen maar in principe gaat t eerst over
1. arduino chips, zoals atmel, maar ook pic en microcontroller boards als STM32
2. daarna over Chinese smartwatch chips van mediatek
3. dan over ASIC’s als GOAC en NOAC h Nes en Genesis on a chip incl de titan nes emulator
4. de processoren in de game en watch en andere lcd games van oa Nintendo,
Geen idee hoe je hier links naar delen van de pagina maakt dus ja zoek maar
GAME AND WATCH
En je vind wel de een of andere interresante spec of toelichting. Have fun.
O, en het zijn dus allemaal low spec cpu en GPU’s, maar dan anno nu, dus 8 bitters @ 32 mhz met 4 PWM output. Of cortex m0 cores, de goedkoopste en kleinste en zuinigste ARM core die bestaat van een kwart vierkante mm en die toch krachtig genoeg is om er een nes emulator op te draaien.
Kun je nagaan wat zon MCU van 50 cent zou kunnen presteren als je dr native op zou coden, die daar zou je een homecomputer op kunnen bouwen die sneller is dan een at pc of en c 64, puur op processorkracht een aansluitpoorten. En dat wordt dan in een thermostaat of koffiezet apparaat gebruikt, What a waste of recources, ik bedoel er zijn zelfs game computers in kleur die puur op een 8 bits atmega328 en een paar weerstandjes draaien en die hun tv en audio output genereren uit de PWM signalen die uit de pootjes van de chip komen die eigenlijk bedoeld zijn om knipperlichten en servomotoren aan te sturen, en dan bedoel ik games als pacman of Space invaders, op je tv!
Edit: ik besef net dat deze blog waarschijnlijk de grootste hoeveelheid aan keywords en typeomschrijvingen heeft die ooit op tweskers blogs heeft gestaan en waar dus misschien nog wel erg veel internationale hits van Specs zoekers zou kunnen genereren dan ik eigenlijk bij stil gestaan heb:]

The ATMega328P and ATMega32U4 are both in the AVR family and have 32K of flash memory (hence the 32 in the name). They differ in package and what peripherals are offered. The biggest difference is that the 32U4 has a USB Device peripheral (hence the U in the name) the 328P does no have a dedicated USB peripheral, although a bit-bang library (V-USB) does exist. If you want to use the chip for a USB keyboard, the ATMega32U4, or any of the other USB equipped devices in the AVR family is a better choice.
Edit: The AU suffix seen in the part number ATMega32P-AU is simply a package/case designation. The P is for PicoPower which is a set of features that allows for saving power including turning off peripherals that are not in

Even if we usually don’t point out to blogs in our news channel, this post from Bunnie Wang, creator of the Novena open source laptop and renowned hacker worldwide contains not only the great description of chinese “Gongkai” culture, but also a great example of reverse engineering applied to a MT6260 to create a reference hardware design called “Fernvale”. Really must read for all hardware hackers!
the Chinese have a parallel system of traditions and ethics around sharing IP, which lead me to coin the term “gongkai”. This is deliberately not the Chinese word for “Open Source”, because that word (kaiyuan) refers to openness in a Western-style IP framework, which this not. Gongkai is more a reference to the fact that copyrighted documents, sometimes labeled “confidential” and “proprietary”, are made known to the public and shared overtly, but not necessarily according to the letter of the law. However, this copying isn’t a one-way flow of value, as it would be in the case of copied movies or music. Rather, these documents are the knowledge base needed to build a phone using the copyright owner’s chips, and as such, this sharing of documents helps to promote the sales of their chips. There is ultimately, if you will, a quid-pro-quo between the copyright holders and the copiers.

The GOACs in today's Geniclones already have the 68000 and Z80 in them, but some GOACs are so cheaply made, they omit signals (TCT-6801) or have functionality that doesn't even work even though it normally would work (Master System compatibility on the TCT-6705 GOAC - pin B30 is connected to the GOAC, but Master System games refuse to work regllardless of that). They seem to be based off TecToy's 580G GOAC, which means they all have a 68000, Z80, YM3438 (my big problem with GOACs as the Genesis originally came with the YM2612 and NOT the YM3438) and Sega's VDP (slightly different as the vertical overscan area and some solid color screens show up black).
nds entirely on the GOAC. If there's a TCT-6801 ( No Virtua racing )like on the MegaDrive X shown in the video, the best you can do is S-Video. However, some of these also have the SM801-A1, which is the most complete clone GOAC, RGB included. I found a mod to get RGB off the SM801-A1 on a Russian forum, but I'll have to find the link to that mod again. I remember it involving 3 transistors and some resistors.
Since its just a couple of screws I opened up the MD X - this particular one is a TCT-6801 so no RGB options unfortunately
Since i am a huge fan of your hardware mods / clone console test i spent this evening checking the stuff you asked about.
TCT-6801 DW-16T-6801-01FIY 2009-05-05 Rev 1.0
I dont know if it output PAL video since my Tvs supports NTSC / PAL and my Tvs that doesn't do that are RF only.
The overclock in my opinion doesn't seems to do nothing. (Either my switch is bad or i am stupid)
Virtua Racing doesn't work. I tried the 50 / 60 Hz switch and the "PAL" / "NTSC" switch and i only got a black screen.
Also it will work with the Megadrive II / Genesis II composite cable but the stereo sound is dual mono.
Ace you should really get one and work your magic on it

Titan was supposed to be a family of 32-bit Power Architecture-based microprocessor cores designed by Applied Micro Circuits Corporation (AMCC), but was scrapped in 2010 according to reports. Applied Micro chose to continue development of the PowerPC 400core instead, on a 40 nm fabrication process.
It was designed to be the foundation of embedded processors and system-on-a-chip (SoC) solutions. While being high performance, reaching speeds up to 2 GHz, it would remain extremely power efficient, drawing just 2.5 W per core. Where there usually is a trade-off between performance and power, AMCC used the Fast14 technology from Intrinsity to build an extremely efficient microprocessor design leveraging high performance combined with low power and comparably cheap bulk 90 nm CMOS manufacturing. By using NMOStransistors and no latches, the design results in a chip with fewer transistors than traditional design, thus reducing cost. The design allows for dual core SoC implementations consuming less than 15 W. There were plans for single, dual and quad-core versions.
The Titan had a new superscalar, out of order 8-9 stage core with a novel three-stage CPU cache design. Small 4/4 KiB instruction and data caches at "level 0" sit before the traditional 32/32 KiB L1 caches up to 1 MB L2 cache that will be shared between all cores (supporting up to four). The Titan was compliant with the Power ISA v.2.04.
• APM 83290 – The first implementations of the Titan core design, codenamed Gemeni. Two 1.5 GHz cores with FPU, 512 kB shared L2 cache, DDR2 controller, security engine, multi-channel DMA and I/O engine for gigabit Ethernet, PCIe, USB, RapidIO and SATA. It began sampling in October 2009 . The processor is aimed at telecom and control plane applications. It is built using TSMC's 90 nm bulk CMOS fabrication to reduce cost.

3. GAME AND WATCH
Game & watch
I was involved with hardware remakes / clones of a few machines and we did reverse engineer one G&W game; I think it was Green House, if I remember well.
The games are build around a custom ASIC and the rest of the circuitry is essentially support for it.
As a side note, if you've ever opened a G&W game double screen game, you'll have noticed that the main chip is sitting 45° from the main board and this was done because at the time the boards were soldered through a wave soldering machine and it allows all the pins to be properly soldered without bridges between them.
Let me tell you how they work but be prepared that it will totally kill the magic:
The whole game is essentially a polynomial generator and a few shift registers.
The polynomial unit will generate the same bit stream every single time it is started. Its output is fed to a de-multiplexer and each output feeds a shift register. Each bit in these registers is tied to an element in the LCD.
All motion done by the player is also mapped in a shift register and then a simple hardwired AND determines collisions. Possible actions in a given state are encoded in a matrix and the logic can swap bits at specific positions.
The game gets faster and faster by just changing the clock (which is essentially gated by another shift register).
Now with this information in mind, play the games again and you'll be able to see the logic at work where the player is essentially always on a long bit string and that when the objects become faster, so does the player input, etc.
We didn't reverse other games, but I see no reason why they'd have a different hardware since only one small matrix on top of that system can make a different game; Zelda is different, but it came years after the rest and I have no clue how it is made.
There is a bit more logic to it, but that's essentially it; some of the logic is to drive the screen; I don't remember the reason but I was explained that LCD screens from that era needed the segments to be toggled on / off to prevent some damage, apparently it's the same in watches; if anyone worked with that technology, I'd be happy to understand the details.
The hardware is tiny and could be re-implemented in a FPGA in an afternoon, but it was really clever since there is no CPU involved; It would be trivial to recreate the ASIC in software as well with very little code where each game is a different table.
Finally, why simulating instead of emulating?
Because of the great lack of informations about the wide range of 4-bit microprocessors used as "engine" in handheld video-games.
The Game & Watch is more akin to a light switchboard than to a computer.
Hello, maybe I can help. I'm the owner of MADrigal's Simulators.
The problem is that the CPU used in Niintendo G&W is still unknown. Some people suspect it's a TI TMS1000 or a Sharp MC-501.
They are normal 4-bit MCU's with opcodes, RAM and ROM.
The problem is that the ROM is embedded in the MCU, so you should "decap" them and "extract" the data visually, in a similar manner to what the MAME team does to decode rare MCU's (like Bubble Bobble, for example).
It's feasible but expensive.
To date, no one has ever emulated any of those MCU's.
Thanks for reading.

Big update since last time! I'm up to over 20 games dumped and vectored and traced out now!
I have figured out how to dump the MM78 CPUs that were in the Mattel Football game, and have dumped the COP411 in the Entex Turtles game. This brings the total CPU dumpability list up to:
HD38800B hitachi ?
D553C NEC (verified)
COP411 national semiconductor 1992
Epoch Dracula (D553C)
Tomy Alien Chase (D553C)
Tomy Tennis (D553C)
All three games use the same CPU, the NEC D553 (D552 on Tennis
In September of 1971, TI finished the design for their TMS0100 single-chip calculators. Designs where done by the Texas Instruments engineers Gary Boone and Michael Cochran. Based on their design of the TMX1795, Gary patented the invention for a single-chip processing machine on Aug 31, 1971. On Sep 4 1973, he was awarded U.S. Patent 3,757,306. Building on top of their experiences with the TMS0100 and Boone's 8-bit microprocessor prototype they went on to design the 4-bit TMS1000 microcontroller series. Boone was later awarded U.S. Patent 4,074,351 for the modern microcontroller.
After being slightly refined, the chip was released to general market in 1974. A few dozen different variations were created with various ROM and RAM sizes. Due to its cheap price, the TMS1000 family enjoyed a tremendous success in consumer electronics.
The TMS1000 was cheap enough to be used in everything from TI's own calculators to microwave ovens, washers, jukeboxes, video games, toys, games, and thousands of other electronic products. Over one hundred million processors were sold.
Distinctive features: The TEAL PHOTON appears to have been the first solar cell powered calculator.
Display is 8 digits, LCD with yellow filter.
There are two versions, with version 2 having the extra "AC" key, but both are 4-function, with %, memory, and square root keys.
Power supply is solar cell, only.
Version 1 integrated circuit is a Toshiba T3606, here date coded late 1977.
Version 2 integrated circuit is an NEC D1831G, here date coded late 1979.
