The Lattice Semiconductor RISC-V MC CPU soft IP contains a 32-bit RISC-V processor core and optional submodules – Timer and Programmable Interrupt Controller (PIC).

The design is implemented using Verilog HDL, and it can be configured and generated using the Lattice Propel™ Builder software. It supports Lattice Avant™, MachXO5™-NX, Certus™-NX, CertusPro™-NX, CrossLink™-NX, MachXO3D™, MachXO3™, and MachXO2™ FPGA devices.

Resource Utilization details are available in the IP Core User Guide.

Features

  • RV32IMC instruction set
  • Five stages of pipelines
  • Support the AHB-L bus standard for instruction/data port
  • Optional caches, including a 4 KB two-way instruction cache and a 4 KB two-way data cache (for Lattice Avant, MachXO5-NX, Certus-NX, CertusPro-NX, and CrossLink-NX only)
  • Optional debug using Gnu Debugger (GDB) and Open On-Chip Debugger (OpenOCD)
