Abstract: The microprocessors are used for executing instructions by fetching from memory. The processor interact with other peripherals, it requires additional circuitry .This makes system complexity ,requires large area and high power consumption .To overcome this problem the microprocessor itself capable to handle peripherals up to its limit. This feature comes in Pico Blaze microprocessor. Pico Blaze is a 16-bit soft core microprocessor developed by Xilinx that can be synthesized in some FPGA families. In this design a set of peripherals that have been developed to interface with Pico Blaze. They are PS/2 keyboard port, Light monitor control serial communication. The system has been implemented in a FPGA board and some typical control and monitoring systems have been developed. Pico Blaze is aimed to replace large finite-state machines in low- to mid-complexity designs by the advancement of programmable logic devices CPLD /FPGA and with the help of hardware descriptive languages. The system has been implemented in a FPGA board and some typical control and monitoring systems have been developed.
