">the award-winning SERV is [possibly!] the
world's smallest RISC-V CPU.
It's the perfect companion whenever you need a bit of computation and silicon real estate is at a premium.
How small is it then? Synthesizing the latest version of SERV in its most minimal form, yields the following results for some popular FPGA architectures and a typical CMOS process.
Lattice iCE40 - 198 LUT, 164 FF
Intel Cyclone 10LP - 239 LUT, 164 FF
AMD Artix-7 - 125 LUT, 164 FF
CMOS - 2.1kGE"

>"SERV (RV32I, RV32IM, RV32Zicsr)
The award-winning SERV CPU by Olof Kindgren is a bit-serial RISC-V CPU that is focussed on being as minimal as possible."
Maximum clock frequency: 1020 MHz (1.02 Ghz) (<-Fastest clock speed of all compared Open Source/Open Hardware RISC-V CPU's in this article...)
Die area: 0.029584 mm^2
Utilization rate: 78.868%"
