Product function

2.5.1 RISC-V4F processor

             RISC-V4F supports the IMAFC subset of the RISC-V instruction set and adds single-precision floating-point operations. The processor is managed in a modular way internally, including units such as the Fast Programmable Interrupt Controller (PFIC), memory protection, branch prediction mode, and extended instruction support. Multiple sets of external buses are connected to external unit modules to achieve interaction between external functional modules and the kernel.

            The Qingke microprocessor, with its features such as an extremely simple instruction set, multiple working modes, and modular customization and expansion, can be flexibly applied in the design of microcontrollers for various scenarios, such as small-area low-power embedded scenarios and high-performance application operating system scenarios.
