This paper describes the design of a light weight, open-source implementation of a RISCV processor using modern hardware design teclmiques, the implementation of the design onto a Field Programmable Gate Array (FPGA), and its testing.
RISC-V is an open-source instruction set architecture (ISA) that allows anyone to implement a central processing unit (CPU) or system-on-a-chip (SOC) design without paying a licensing fee. As a result, it is popular with FPGA enthusiasts as the starting point for a softcore processor implementation.

RISC-V Instruction Set Architecture (ISA)-based microarchitectures are an important part of all Field Programmable Gate Array (FPGA)-based research projects in the Red Hat Collaboratory at Boston University. Having CPU cores in FPGA designs is important: partitioning workloads between special purpose FPGA circuits and these general purpose cores al...
Before we get into detail, however, let’s review four fundamental aspects of the computer architecture ecosystem: 1. Microarchitectures 2. Toolchains 3. Runtime environments 4. ISAs A microarchitecture is the organization of the actual hardware of a processor. It specifies the various hardware blocks used, their parameters/sizes, and how these bloc...
So how did we end up choosing the RISC-V ISA and its ecosystem? The first requirement was that the ISA needed to be open source. Having an open source solution is essential for enabling support for customizations to the softcore microarchitecture based on target workloads and constraints. As a result, we could not use ISAs such as ARM and x86. The ...
As noted previously, softcores are CPU cores that are coded using HDLs and instantiated on FPGAs using chip resources such as LUTs, memory blocks, DSPs, and interconnects. Because the softcore can vary in features and sizes, multiple softcores can be instantiated on a single FPGA fabric, limited by the total available FPGA resources. FPGA-based sof...
Jan 25, 2022 · A field-programmable gate array (FPGA) is an integrated circuit (IC) that lets you implement custom digital circuits. You can use an FPGA to create optimized digital logic for things like digital signal processing (DSP), machine learning, and cryptocurrency mining.
The RISC-V architecture is sweeping the embedded world and is making its way into FPGA development. New vendor IP from innovative FPGA manufacturers now implements RISC-V in FPGAs for more efficient high-density compute.
FemtoRV is a minimalistic RISC-V design, with easy-to-read Verilog sources directly written from the RISC-V specification. The most elementary version (quark), an RV32I core, weights 400 lines of VERILOG (documented version), and 100 lines if you remove the comments.
