The SCR3 Microcontroller Core is an efficient RISC-V processor tailored for embedded applications that demand high performance in power-sensitive environments. This 32/64-bit microcontroller-class core features a sophisticated 5-stage in-order pipeline with support for atomic instructions, compressed extensions, and integer multiplication and division. The design is enriched with a dynamic branch predictor and supports up to 4-core symmetric multiprocessing for improved performance and memory coherency.\n\nThe SCR3's memory architecture includes tightly coupled memory (TCM) with error correction features, L1/L2 caches, and a configurable memory protection unit that supports various privilege modes. A robust interrupt system is facilitated by industry-standard interfaces such as AHB, AXI4, and JTAG, making it a powerhouse for real-time operating systems and heterogeneous cluster integration.\n\nApplications of the SCR3 core expand into industrial automation, IoT, smart meters, and storage devices. The processor's optimization for energy efficiency, small area, and high performance addresses the unique requirements of these fields, ensuring smooth operation of automation systems, smart home applications, and automotive systems.
