RISC-V 32-bit Architecture IPs
E330:
ESWIN E330 is an energy-efficient 32-bit RISC-V embedded CPU IP for general purpose.
The RISC-V 32 IMA(FD)CB(P) instruction set, the Zicond conditional execution extension, Zicbom cache operation extension and Smepmp security extension are supported.
To make it easier for users to debug RTL simulations, ESWIN Sight function is provided to easily probe the internal state and events of the CPU.
E330 is superscalar 6-stage pipeline arichitect with branch predictor inside, which can be applied to a wide range of high-performance embedded applications.
