description: The given work is devoted to providing an overview of the architecture and the generalized implementation of the RISC-V microarchitecture, in addition to introducing the multiply-accumulate operations in the microcontroller core SCR1 from the manufacturer Syntacore. In this thesis, a set of architecture instructions and the fundamentals of building the RISC-V microarchitecture were taken into consideration. The source code of the SCR1 microcontroller core, that was realized in SystemVerilog language has been changed for the purpose of introducing additional instructions that are especially designed to perform signed and unsigned multiply-accumulate operations. Simulation results of the SCR1 microcontroller core that were obtained using Verilator software, are provided in this work, they confirm the correct implementation of multiply-accumulate operations. While the logical synthesis results of the modified microcontroller core SCR1 for the Arty A7-35 board with programmable logic devices (PLDs) from Xilinxâs Artix family show the efficiency of implementing multiply-accumulate operations. The microarchitecture implementation of the multiply-accumulate operations in the microcontroller core, that is carried out in accordance with the RISC-V architecture, allows these operations to be used free of charge for solving different tasks in different fields such as: digital signal processing, neural networks and cryptography.
