64-bit Multiprocessor with Level-2 Cache-Coherence

AndesCore™ AX25MP 64-bit multicore CPU IP is based on AndeStar™ V5 architecture. It supports RISC-V standard 'IMAC-FD' extensions, Andes contributed DSP/SIMD 'P' extension (draft), user-level interrupt 'N' extension, and Andes performance/ functionality enhancements such as instructions for faster memory accesses, faster branch handling, and Andes Custom Extension™ (ACE) to add user-defined instructions. It features MMU for Linux based applications, branch prediction for efficient branch execution, level-1 instruction/data caches and local memories for low-latency accesses.

The AX25MP symmetric multiprocessor supports up to 4 cores and a level-2 cache controller with instruction and data prefetch. Andes Coherence Unit (ACU) manages level-1 cache coherence, including I/O coherence for cacheless bus masters, and duplicated L1 tag to screen allocated lines for snoop queries. Other AX25MP features include ECC for level-1/2 memory soft error protection, Platform-Level Interrupt Controller (PLIC) with enhancements for vectored dispatch and priority-based preemption, CoDense™, StackSafe™ for software quality improvement, and QuickNap™, PowerBrake, and WFI for power management.
