SiFive HiFive Unmatched

At the heart of the SiFive HiFive Unmatched board is the new SiFive FU740 SoC, a five-core heterogeneous, coherent processor with four SiFive U74 cores, and one SiFive S7 core. If you’ve been following SiFive for a while, you’ll know that the U-Series are SiFive’s Linux-capable 64-bit application processor cores, based on the RISC-V ISA that the founders of SiFive invented. SiFive S-Series cores are 64-bit real-time embedded cores designed to enable mission critical or deterministic processing. Combined in the SiFive FU740 using SiFive Mix+Match technology, the heterogeneous multicore complex offers a potent combination of application and real-time processing.
This board is available for pre-order through SiFive.
