High performance dual-issue, out-of-order, 7-stage Vector processor (DSP) IP

World's first audio DSP IP with RISC-V Vector processor architecture
RiVAI-V1 is a dual-issue, Out-of-Order execution, 7-stage pipeline, 32-bit RISC-V processor core that supports the RV32IMFAC instruction set and customized Vector extension, as well as partial P extension. It is a real-time high-performance DSP IP, which can boost the performance of voice, audio, video, image and AI processing. Its “F” extensions support IEEE 754-compliant single precision floating point instructions, as well. The width of the Vector Register is 512 bits, including register renaming, and the memory access width is 256 bits. This greatly enhances memory bandwidth and reduces memory latencies for applications with intensive memory accesses. In addition, RiVAI-V1 features an advanced low-power, dynamic branch-prediction mechanism for efficient branch execution, instruction and data caches, local memories, and ECC error protection. It also includes a vectored and preemptive interrupt controller to serve diversified system events, an AHB bus, rich power management, and JTAG debug and trace interface for software development support.
