Description:	. AMD 8088 microprocessor is almost identical to the AMD 8086 processor with the exception of the external data bus. External data bus width of the 8088 was reduced to 8 bits, and instruction queue size and prefetching algorithms were changed. Intel 8088 used two consecutive bus cycles to write or read 16 bit data instead of one cycle for the 8086. This made the processor to run slower, but on the plus side the hardware changes in the 8088 CPU made it compatible with 8080/8085 peripherals.
