eSi-RISC designs and licenses the eSi-RISC range of configurable, low-power, RISC CPU IP cores, as well as associated peripheral IP cores and software development tools. The eSi-RISC processors are unique in being configurable from a base 16-bit core (eSi-1600) to a 32-bit, multi-core CPU with optional caches (eSi-3250), to a high-performance DSP core with 64-bit fixed-point SIMD and floating point support (eSi-3264).
As well as supplying individual cores, eSi-RISC can develop complete SoC sub-systems combining CPUs, memory and peripherals (DMA, memory-controllers, I2C, UART, SPI, etc.), using an AMBA AXI/AHB/APB based interconnect, generated automatically using our eSi-SoC EDA tool.
