2.1.1 RISC-V Core Benchmark

The following tests were conducted on the MX10-U (with 10M50DAF256I7G, Speedgrade 7) using Quartus
20.1 Lite.
Quartus Compilation effort was set to Performance (Aggressive) with most options that increase max-
imum frequency turned on. The clock frequency of the FPGA system was 25 MHz. The benchmarks were
compiled using GCC version 11.1.0 with the compiler flags -O3

2.1.1.1 Dhrystone

Core @ 25 MHz
Serv (RV32I)
PicoRV Small (RV32I)
PicoRV (RV32IM)

2.1.1.2 CoreMark

Core @ 25 MHz
Serv (RV32I)
PicoRV32 Small (RV32I)
PicoRV32 (RV32IM)
VexRiscv (RV32IM)
VexRiscv+Cache (RV32IMAFC)

2.1.2 FPGA Resource Usage

For the resource usage statistics the Quartus Compilation effort was set to Area. The data was taken from
the fitter report.
