Circuit Cellar Article: RISC-V Processor Family Spans From Low-End To 64-Bit With FPU

As part of its Cortus IC Design Service offering, Cortus has announced the general availability of a complete range of RISC-V processors. These are now available for design-in in customer ASIC designs implemented by the experienced teams at Cortus. A wide range of application needs are covered by the 6 processor cores.
The range starts with a low gate count, very low power 32 bit CPU core—the APS1V (RV32EMC). A more powerful, but equally low power CPU, the APS3V (RV32IMC) comes next. If a multi-core solution is necessary the APS5V (RV32IMAC) is available. If floating point is needed then the single precision FPS6V (RV32IMACF) can be used or the FPS8V (RV32GC) for double precision calculations. The last member of the family is a high performance 64-bit processor with double precision floating point and MMU: the FPS69V (RV64GC).
