RISC-V Interrupts These are the interrupts that are defined by the base ISA. Assertion and Service mcause.Exception_Code (Where Interrupt==1) describes the possible interrupt sources. When the interrupt condition is met, a bit in the interrupt pending register (mip) is set. To service an in...
Fully Parameterized & Programmable Platform Level Interrupt Controller (PLIC) for RISC-V based Processor Systems supporting a user-defined number of interrupt sources and targets, and featuring a single AHB-Lite Slave interface The core supports a programmable number of simultaneous pending interrupt ...
To reduce latency, the PLIC core presents all asserted interrupts to the target in priority order, queuing them so that a software interrupt handler can service all pending interrupts without the need to restore the interrupted context. 查看RISC-V Compliant Platform Level Interrupt Controller详细介绍...

When generating a generic RISC-V project with the project wizard you will get a simple working "Hello World" project. The Startup of the application happens in file SEGGER_RV32_crt0.s If you look into that file you will find the following code line: ...
An interrupt system for RISC-V architecture includes an original register in a CLIC, a pushmcause register, a pushmepc register, an interrupt response register, and an mtvt2 register; the pushmcause register is used to store a value in an mcause on a stack by means of an instruction; ...

To overcome this limitation, we present the design, implementation, and in-system assessment of vCLIC, a virtualization extension to the RISC-V CLIC fast interrupt controller. Our approach achieves 20x interrupt latency speed-up over the software emulation required for handling non-virtualization-...
