InCore Semiconductors

InCore Azurite is an extremely compact, RISC-V 2-stage pipelined micro-processor. Built on Incore’s proprietary deep-customization stack for microarchitectural exploration, Azurite delivers industry-beating performance in an exceptionally small silicon footprint. A 32-bit processor at the cost of a traditional 8-bit price point.

Azurite is comparable to ARM Cortex M-0, M-0+, M-23, M-3 and M-4 cores.

The Azurite core comes bundled as a compute subsystem, with integrated AMBA protocol interconnects (supports AXI4, AHB, APB) and uncore components (debug, trace, interrupt controllers etc)
