The Intel® C8008 is a single chip MOS 8-bit parallel central processor unit (CPU) for the MCS-8 microcomputer system.
This CPU contains six 8-bit data registers, an 8-bit accumulator, two 8-bit temporary registers, 4 flag bits (carry, zero, sign, parity), and an 8-bit parallel binary arithmetic unit, which implements addition, subtraction, and logical operations. A memory stack containing a 14-bit program counter and seven 14-bit words is used internally to store program and subroutine addresses. The 14-bit address permits the direct addressing of 16K words of memory (any mix of RAM, ROM, or S.R.).
The instruction set of the C8008 consists of 48 instructions including data manipulation, binary arithmetic, and jump to subroutine.
The normal program flow of the C8008 may be interrupted through the use of the interrupt control line. This allows the servicing of slow I/O peripheral devices while also executing the main program.
The ready command line synchronizes the 8008 to the memory cycle allowing any type or speed of semiconductor memory to be used [3]
