Is the MOS 6502 still made?
As one of the most widely used microprocessor architectures of all time, the CMOS related form of the 6502 developed by the Western Design Center is still in production today, with an estimated six billion units so far produced.What is the structure of mos 6502?
The 6502 Architecture
The 6502 is strictly an 8-bit architecture, with a single 8-bit accumulator register, and can access a maximum of 64K bytes of random access memory. Memory addresses are exactly 16 bits in length, because 216 = 65536 = 64K. Valid addresses range from 0 up to 65535.What is MOS 6502 used for?
Popular video game consoles and home computers of the 1980s and early 1990s, such as the Atari 2600, Atari 8-bit family, Apple II, Nintendo Entertainment System, Commodore 64, Atari Lynx, BBC Micro and others, use the 6502 or variations of the basic design.- Generally speaking, Z80 is two to three times slower than 6502 since its fastest instruction is 4 cycles and 6502's is just 2. Then, if you take into account additional instruction bytes and memory addressing, Z80 looks like it's completely behind. But things in real life differs a bit.
