In order to achieve the integer multiplication operation in the RV32IM processor
The "M" standard extension of the integer multiplication of the RISC-V instruction set is implemented. For achieving the design for multiplication instructions
it uses the Booth algorithm of Base 4 and the Wallace Tree 4-2 Compressor.The design embedded in the RV32IM processor
through the simulation and SMIC 65nm high density standard cell library to show that:The multiplication circuit functions correctly and significantly improved the operation efficiency of the multiplication
the maximum operating frequency can reach 500MHz.
