Abstract: The aim of this study is to develop a MIPS pipeline processor based on FPGA with using VHDL. This architecture can be used for academic purposes and to set up a multifunctional system for the processing of digital signals or images. In order to do so, a subset of MIPS instructions is chosen to show functionality in the simulation and synthesis processor inside a five-stage pipeline (instruction fetch, instruction decode, execution, memory and writing back). The hazard control network has been set up to manage data transfer and stalling. A single cycle multiplication functionality and a single-cycle SIMD instruction have been added to the basic MIPS architecture. The SIMD instructions have been selected to execute binary operations for possible mathematical morphology. A Software (XUP) box containing Xilinx Virtex7 xc7vx330t FPGA was the board used to test the processor. This makes it possible for the processor to perform four 32-bit data sets per cycle when the SIMD pipeline is complete. The research explained the Field Programmable Gate Array (FPGA) technology with extensive explore of MIPS pipeline architecture. In addition to the research highlights many aspect of this process such as the role of The SIMD principle in the support of the hardware acceleration feature that required by multicore overall processors and instruction set and the multiple instructions executed in this processor from each register and multiply them as standard MIPS applications instead of the entire 32 bits.
