Obviously a Major Malfunction...: January 2013
http://adamsblog.aperturelabs.com/2013_01_01_archive.html
Obviously a Major Malfunction. Random musings that would otherwise have no means of escape from my head. Sunday, 27 January 2013. Fun with Masked ROMs - Atmel MARC4. We have Code Monkeys and Chip Monkeys. Chip Monkeys do the dangerous stuff, while we Code Monkeys sit in our nice safe offices playing with bits and bytes and other things that can't hurt us. Or fiddling with circuits that are directly connected to mains electricity? So when head Chip Monkey Zac Franken. In our case it's a combination of thi...

Chargers, microprocessors, Arduino, and whatever. Down to the silicon: how the Z80's registers are implemented. The 8-bit Z80 microprocessor is famed for use in many early personal computers such the Osborne 1, TRS-80, and Sinclair ZX Spectrum. The Z80 has an innovative design for its internal registers, with two sets of general-purpose registers. The diagram below shows a highly-magnified photo. Of the Z80 chip, from the Visual 6502. Programmer's model of Z80 architecture from Wikipedia. At the right of...

Just like it says. Category: Commodore (General) ( 28. Commodore gaming and forum. Sells 1581 Kits and other things for Commodore. Nice GUI front end for OpenCBM. Very nice collection of GEOS files and I believe the whole Genie archive. Nice link to Andrew Wiskows Cottonwood site. Has some good links for various downloads. This is currently one of the best Commodore related websites on the net (Next to this one of course). Nice site with information on transfering files between a PC and Commodore. The de...

Visual6502.org: Atari 2600 Simulation
http://blog.visual6502.org/2014/10/atari-2600-simulation.html
Digging into or otherwise dissolving (with hot sulfuric acid) ancient microchips. Saturday, October 11, 2014. Full source code and data for our transistor-level simulation of the Atari 2600 is up on github:. The simulation provides a cycle-accurate picture of what the console is doing based on the physical parts of its microchips. October 12, 2014 at 2:13 PM. After thinking about this a bit, I would guess it is due to some phase offset between the 6502 and TIA clocks. The TIA outputs 3 pixels for eac...

Analysis of Trends in Technology, Business, Society. By BoLOBOOLNE payday loans. Brain Simulation Tactics and Complexity Estimates. Ray Kurzweil recently predicted that we’d be able to reverse engineer the human brain by 2020. He makes an argument that a brain simulator would need about a million lines of code:. About half of that is the brain, which comes down to 25 million bytes, or a million lines of code. The biggest flaw in Kurzweil’s argument is that he magically throws in a factor of 16x imp...

Do Not Set Yourself On Fire: CPU emulation is subtle
http://blog.julien-oster.de/2010/11/cpu-emulation-is-subtle.html
Do Not Set Yourself On Fire. It might not be beneficial. CPU emulation is subtle. Taking a first look at the Gameboy's core CPU, emulating it looks pretty straightforward at first. You have some basic processor state (mostly registers), a reasonable amount of instructions to modify said state and some outside interaction, like memory access and interrupts. However, if you want to do it exactly. Right, that is, if your emulated CPU should ideally be able to fully mirror a Gameboy's behavior for all. At fi...
