The QiLai SoC chip includes high performance quad-core RISC-V AX45MP cluster and one NX27V vector processor. The AndesCore™ AX45MP superscalar multicore contains a 2MB Level-2 cache, a coherence manger to manage Level-1 cache coherence, and a MMU (Memory Management Unit) for Linux based applications. The AndesCore™ NX27V vector processor with 512KB data cache supports a full range of RISC-V standard data types and Andes-enhanced data types optimized for AI workloads. The NX27V contains an efficient scalar unit and an out-of-order Vector Processing Unit (VPU) with 512-bit vector length (VLEN) and 512-bit data path width (DLEN), capable of generating up to 4 512-bit results per cycle. The NX27V can cooperate with the AX45MP cluster and make QiLai a heterogeneous software development platform where a Linux SMP system and an RTOS or bare-metal system can run simultaneously. The AX45MP and NX27V can run up to 2.2 GHz and 1.5GHz respectively, and the total power consumption of the QiLai SoC is around 5W when running at its full speed.
