Abstract: A 16 bit low power pipelined RISC processor is proposed by us in this paper, the RISC processor consists of the block mainly ALU, Universal shift register and Barrel Shifter. We have used modified Harvard architecture that uses separate memories for its instruction & data memory response where as in the other architecture by von Neumann, has only one shared memory for instruction and data, with one data bus and address bus with between data memory & processor memory. The remedial architectural modification has been made in incremental circuit utilized in carry select adder unit of the ALU in the RISC Processor. Operation in the core RISC Processor Fetch, Decode, execute, write back is implemented in the 2 stage pipelining with the positive edge & negative Edge. The process has been realized using XILINX ISE Design suit 13.2 & the Dynamic power is minimized in the RISC Core through the clock gating technique that is an efficient power technique and the total power estimation is done by the X Power analyzer. All the implementation is done in XILINX KINTEX XC7K1607-3fbg676 in it kit 28 nm technology are used. The simulation illustrate the total power dissipated by the processor to be 0.220 watt, and the Latency is 1.5 cycle.
