RISC-V Brief Introduction
RISC-V is a free and open Instruction Set Architecture (ISA) enabling a new era of processor
innovation through open standard collaboration. Any organization or individual can design their
own processor based on the RISC-V architecture. Freedom E300, a RISC-V core implemented in
RTL, is realized on T-Core FPGA Board. For more information about Freedom E300, user can learn
more from web (
https://github.com/sifive/freedom
shows the top-level block diagram of the Freedom E300 which contains an E31
Coreplex, a selection of flexible I/O peripherals, a dedicated off-chip Quad-SPI flash controller with
execute-in-place support, On-chip Memory, clock generation, and an always-on (AON) block. In
addition, custom accelerator can be added to provide application-specific processing.
