Maximum Performance Efficiency for Real-time Applications

The Synopsys ARC-V™ RHX series of RISC-V processors are optimized for high performance real-time applications with minimum area and power consumption. The Synopsys ARC-V RHX series provides single core options (Synopsys ARC-V RHX-100) as well as multi-core options which support up to 16x CPU cores in a single processor cluster (Synopsys ARC-V RHX-105).  

The Synopsys ARC-V RHX family also provides support for RISC-V defined vector extensions (RVV) with the Synopsys ARC-V RHX-100V/RHX-105V processor.  All Synopsys ARC-V RHX-100 series cores support RISC-V instruction set architecture (ISA) profiles.

The Synopsys ARC-V RHX processors are supported by a broad ecosystem of commercial and open-source tools, operating systems and middleware. This includes offerings from leading industry vendors who are members of the ARC Access Program as well offerings supporting the broader RISC-V ecosystem.
