Run Linux on a 64-bit Quad-core RISC-V Processor
SiFive has released an open-source RISC-V architecture, 64-bit, quad-core application processor aimed at full-featured operating systems such as Linux. According to SiFive, “The release of the U54-MC Coreplex marks the architecture’s expansion into the application processor space — opening entirely new use cases for RISC-V. It is ideal for applications which need full operating system support such as AI, machine learning, networking, gateways and smart IoT devices.” The standard U54-MC contains four U54 CPUs along with a single E51 CPU and supports cache coherence. Each U54 CPU has a five-stage in-order pipeline, and supports the RV64GC ISA. The 64-bit E51 CPU serves as a management core and is fully-coherent with the main U54 cores.
