Compact High-Speed 64-bit CPU Core

AndesCore™ NX25F is a compact 64-bit CPU IP core based on AndeStar™ V5 architecture which incorporated RISC-V technology, it is tailored for high-performance embedded applications that needs to access address space over 4GB. NX25F also supports single- and double-precision floating point instructions. NX25F comes with options, including branch prediction for efficient branch execution, Instruction and Data caches, Local Memories for low-latency accesses, ECC for L1 memory soft error protection, and Andes Custom Extension™ (ACE) to add proprietary instructions to accelerate performance/power consumption critical spots.

NX25F's 5-stage pipeline is optimized for high operating frequency and high performance. Features also includes PLIC and vectored interrupts for serving various types of system events, AXI or AHB 64-bit data bus for addressing up to 64-bit address, PowerBrake, QuickNap™ and WFI mode for low power and power management, and JTAG debug interface for development support.
