[PDF] 6502 instruction length

Hence 6502 machine instructions vary in length from one to three bytes. The operand is stored in the 6502's customary little-endian format.

  • Is 6502 still used?

    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.

  • Which is faster Z80 or 6502?

    Since most memories perform write operation slowly than the read one, we can say that if we have a specific RAM we can use it with Z80 that runs four times faster than 6502. And since it was the RAM speed that was the bottleneck of computer building at times of Z80 and 6502, a computer with Z80 was faster.

  • What is the maximum RAM for 6502?

    6502 and 6512 processors could address 64KB of memory, other CPUs in the family could address up to 8 KB.
  • The 6502 has an 8-bit addition operation ADC (add with carry) which adds two numbers and a carry-in bit, yielding an 8-bit result and a carry out bit. The following diagram shows an example addition in binary, decimal, and hexadecimal.
