WebMay 3, 2024 · RISC-V Special Instructions and C++. How does the above code generate custom instructions? The riscv-csr.hpp header provides the abstractions. That’s a huge file, but it is generated from a much more compact template file templates/riscv-csr.hpp. To understand how it works lets look at how just one system register, such as mtvec, can be … WebMaybe try adding "zicsr" to -march or see if -misa-spec=20241213 is still the default. You have 2 different --march: GNU toolchain: --with-arch=rv32gc. Bootlin: --with-arch=rv32imafd. The difference is the 'c' compressed instructions.

WebNov 18, 2024 · The template below shows the various methods to access CSRs. A few notes: There are three patterns for register access: read, writing and atomic read then write. Functions for accessing any bit: (write, set, clear) x (no return, atomic read then modify). Macros are defined for accessing the lower 5 bits with immediate data instructions.

WebDec 27, 2024 · The RISC-V Privileged Spec defines additional registers referred to as Control and Status Registers (CSRs). While GPRs are accessible at any privilege level, CSRs are defined at a specific privilege level and can only be accessed by that level and any levels of higher privilege. The Privileged Spec defines both a common set of CSRs …
