About Us

eSi-RISC, founded in London in 2010, is a privately owned and revenue funded semiconductor IP (Intellectual Property) design company. We design and license the eSi-RISC range of configurable, low-power, RISC CPU IP cores for use in ASIC and FPGA SoCs, as well as associated peripheral IP 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, 64-bit fixed-point SIMD and floating point support (eSi-3264). As well as supplying individual cores, we can develop complete SoC sub-systems combining CPUs, memory and peripherals using an AMBA AXI/AHB/APB based interconnect, generated automatically using our eSi-SoC EDA tool.

We have licensed our IP cores across the globe to a wide range of companies, from start-ups to tier 1 semiconductor companies. Our IP licensing is flexible to meet your commercial requirements, with royalty free and sublicensing options.

eSi-RISC CPUs can be found embedded in a wide range of electronics, including: mobile phones, televisions, digital cameras, laptops, secure payment systems, GPS receivers, wireless backhaul infrastructure, traffic tolling systems and a variety of IoT applications. How about your next product?
