E302
RISC-V 32-bit Architecture IPs
E302:
ESWIN Computing E302 32-bit general-purpose processor is a 32-bit RISC-V embedded CPU IP product with low power consumption and ultra-small area.
Supports the RISC-V latest Zc V1.0 compression instruction extension and Smepmp security extension. Compare to E301, E302 has better energy efficiency and higher code density.
Supports two optional Tightly-Integrated Memories (TIMs) which can be used to store instructions or data. And supports external host access TIMs through the front port.
To ease user RTL simulation debugging, it provides an ESWIN Sight function to let users easily probe the internal state, registers and events.
