What happened

Efinix has introduced the Sapphire RV64 SoC, a configurable 64-bit RISC-V soft-core processor designed for its Titanium and Trion FPGAs.^S1 The core is built around the VexiiRiscv architecture and can be configured with one to four RISC-V cores running at a system clock frequency from 20 MHz up to 400 MHz.^S1

Each pipeline implements seven stages: fetch, align-decompress, decode, issue, execute, memory, and writeback.^S1 The core family supports RV64IMACFD plus Zba, Zbc, and Zbs extensions, an optional FPU, branch predictor, prefetchers, and an SV39 MMU.^S1 Configurable L1 caches are paired with an optional 64–512 KB L2 cache, alongside 4–512 KB of on-chip RAM.^S1

On the memory side, the Sapphire RV64 exposes up to 512-bit AXI interfaces to DDR3, LPDDR4x, and HyperRAM, with external memory ranging from 4 MB to 8 GB.^S1 Peripheral integration includes up to 32 GPIOs, five I²C controllers, three SPI controllers, three UARTs, timers, a watchdog, and up to eight user interrupts.^S1 Pricing, licensing terms, and the specific Titanium and Trion device models supported are not disclosed by the source.
