The PIC64GX microprocessor (MPU) is a 64-bit Linux® Operating System (OS)-capable processor that provides an innovative, mid-range, embedded compute platform that is based on the RISC-V® Instruction Set Architecture (ISA). The PIC64GX MPU’s micro-architecture implementation is a simple, five-stage, single-issue, in-order pipeline that is not vulnerable to the Meltdown and Spectre exploits that frequently occur in common, out-of-order machines. The PIC64GX has five RISC-V cores which are coherent with the memory subsystem, allowing a versatile mix of deterministic real-time systems and Linux in a single, multi-core processor cluster. With integrated secure boot, Linux and Real-Time modes, a large and flexible L2 memory subsystem and a rich set of embedded peripherals, the PIC64GX MPU provides new choices for developing secure and power-efficient embedded compute platforms.
