Semidynamics, the only provider of fully customisable RISC-V processor IP, has launched the next member of its Atrevido family of 64-bit cores. The Atrevido 423 has a wider, 4-way pipeline, allowing for the decoding and retirement of up to two times more instructions than its recently launched, 2-way, 223 core. It is also coupled with more functional units, which significantly increases the IPC (instructions-per-cycle).
