Silicon IP Portfolio

eSi-RISC designs and licenses high quality silicon IP.  Our portfolio of IP includes our highly configurable RISC processors, a wide range of AMBA peripherals and interconnects as well as floating-point arithmetic cores.

eSi-RISC Processors

eSi-RISC is a highly configurable 16 or 32-bit processor architecture for embedded systems that scales across a wide range of applications and has been proven in a wide range of ASIC and FPGA technologies.


eSi-Connect provides a suite of integration and connectivity IP supporting AMBA interfaces that simplify SoC development and includes memory controllers, standard off-chip interfaces and control functions.


The eSi-Floating Point IP cores perform half-precision (16-bit), single-precision (32-bit) and double-precision (64-bit) floating-point arithmetic according to the IEEE 754-2008 standard.
