Timer interrupts (Interrupt ID #7) are triggered when the memory-mapped register mtime is greater than or equal to the global timebase register mtimecmp, and both registers are part of the CLINT memory map. mtimecmp can be written by other harts to set up timer interrupts. The mtime and ...

The compressed instruction encodings are mostly common across RV32C, RV64C, and RV128C, but as shown in Table [rvcopcodemap], a few opcodes are used for different purposes depending on base ISA. For example, the wider address-space RV64C and RV128C variants require additional opcodes to...
