CPU Design – the 6502

Incredibly, this chip and other processors are now emulated in software, although slower, to simulate and understand the hardware CPU design. The 6502 was designed by hand in 1975 and used in the Apple, Atari, Commodore 64, and Nintendo systems. The most interesting part of the CPU is the random control logic which carries out the operations from the decoded instruction. This video goes through the small instruction set and explains the hardware implementation and recent method of simulation.
