ARC and Arm are both companies that design and license microprocessor (CPU) architectures. ARC processors are known for their customizability and low power consumption, making ARC an ideal choice for system-on-chip (SoC) designers looking for inexpensive CPU cores. While Arm processors are known for their wide range of implementations and high performance, RISC-V is gaining significant market traction given its performance, extensibility, and open-source business model. Now, Synopsys, second only to Arm in delivering CPU design intellectual property (IP), is adopting RISC-V in their new ARC-V IP to help SoC designers access better performance and a fast-growing software ecosystem.
