There are many soft-core processors or microcontroller available in contemporary technological world. Many of those when used for and on-chip peripheral control and arbitration are either tend to under use when used for command processors because of their powerful features that are not utilized completely or many of the capabilities and feature become redundant in specific applications. The present architecture of such on-chip command processor is a soft core in its ultra simplified architecture. Its ridiculous simple architecture and yet being powerful enough commands for control encourage it use for many on-chip peripheral controlling purpose. The extended use of the mentions command processor can finds use in debugging & testing a design of a digital circuit that is targeted onto FPGA/VLSI device. The present work discussed is about architecture, commands and typical application scenario. This work also covers the RTL implementation, simulation using test bench in VHDL. Along with simulation result it also covers the synthesis aspects of result for target FPGA from Xilinx.
