RISC-V 64-bit Architecture IPs
S500:
ESWIN S500 is an energy-efficient 64-bit Linux capable RISC-V CPU IP.
It adopts self-developed 9-stage pipeline dual issue in order, and supports multicores, and SMP. A core cluster can have up to 4 cores inside.
It enables running Linux and other operating systems that require MMU support.
The trusted execution environment is supported to meet the system security requirements.
The optional E-Trace/N-Trace for advanced debugging function is supported. With the characteristics of high energy efficiency and extensive application fields. It can be applied to AIoT edge computing, network devices and baseband communication, etc.
