Fully optimized risc-v processor core

GD32VF103 series MCU adopts the brand-new based on open source RISC instruction set architecture - V Bumblebee processor core, is a mega easy innovation (GigaDevice) hand in hand, China's leading RISC processor core IP and solution vendors - V core to science and Technology (Nuclei System Technology) for the Internet of things and other ultra low power application scenario independent joint development of a commercial RISC processor core - V.

The Bumblebee kernel USES the 32-bit risc-v open source instruction set architecture and supports customization of instructions to optimize the interrupt handling mechanism.Not only is it equipped with a 64-bit wide real-time timer that generates timer interrupts defined by the risc-v standard, but it also supports dozens of external interrupt sources, 16 interrupt levels and priorities, and supports interrupt nesting and fast vector interrupt handling mechanisms.Low power management can support two levels of sleep mode.The kernel supports standard JTAG interface and risc-v debugging standard, suitable for hardware breakpoints and interactive debugging.The Bumblebee kernel also supports the risc-v standard compilation toolchain, as well as the Linux/Windows graphical integrated development environment.

The Bumblebee kernel is designed with a two-level variable-size pipeline microarchitecture, equipped with a streamlined instruction prefetch unit and a dynamic branch predictor, and incorporates a variety of low-power design methods.It can achieve the performance and frequency of traditional three-level pipeline at the cost of two-level pipeline, and realize the first-class energy efficiency ratio and cost advantage in the industry.This allows the GD32VF103 MCU to achieve a performance of 153 DMIPS at the highest main frequency. CoreMark® test also achieved 360 points of excellent performance. Compared with the GD32 Cortex® -m3 kernel product, the performance is improved by 15%, while the dynamic power consumption is reduced by 50% and standby power consumption is reduced by 25%.
