The RV12 is a versatile, single-issue RISC-V compliant processor core, designed for the embedded market. With compliance to both RV32I and RV64I specifications, this core is part of Roa Logic's 32/64-bit CPU offerings. Featuring a Harvard architecture, it efficiently handles simultaneous instruction and data memory operations. The architecture is enhanced with an optimizing folded 4-stage pipeline, maximizing the overlap of execution with memory access to reduce latency and boost throughput.
Flexibility is a cornerstone of the RV12 processor, offering numerous configuration options to tailor performance and efficiency. Users can select optional components such as branch prediction units, instruction and data caches, and a debug unit. This configurability allows designers to balance trade-offs between speed, power consumption, and area, optimizing the core for specific applications.
The processor core supports a variety of standard software tools and comes with a full suite of development resources, including support for the Eclipse Integrated Development Environment (IDE) and GNU toolchain. The RV12 design emphasizes a small silicon footprint and power-efficient operation, making it ideal for a wide range of embedded applications.
