A Chip Designer’s Perspective of RISC-V Traps |

Описание: In this video, Founder and CEO of Maven Silicon, Sivakumar P R, explains RISC-V traps from a chip designer’s perspective and why they are critical for building RISC-V CPUs, microcontrollers, and complex SoCs, as well as for developing and debugging firmware, RTOS, and OS kernels.

The session covers what traps are, the difference between exceptions and interrupts, and how the CPU handles them using key CSRs such as mepc/sepc, mcause/scause, mtval/stval, and mtvec/stvec. It also explains trap vector setup, interrupt enabling, privilege-mode delegation, and the role of PLIC and timers in real hardware systems.

Real-world scenarios are discussed across bare-metal systems, OS-based system calls using ecall, and RTOS environments where interrupts are delegated from M-mode to S-mode. With practical insights and RISC-V assembly examples, this video bridges architectural concepts with real silicon and software implementations, helping professionals gain a clear and practical understanding of RISC-V trap handling.
