== Introduction

Hazard3 is a 3-stage RISC-V processor, providing the following architectural support:

* `RV32I`: 32-bit base instruction set
* `M` extension: integer multiply/divide/modulo
* `C` extension: compressed instructions
* `Zicsr` extension: CSR access
* M-mode privileged instructions `ECALL`, `EBREAK`, `MRET`
* The machine-mode (M-mode) privilege state, and standard M-mode CSRs

The following are planned for future implementation:

* Support for `WFI` instruction
* Debug support
* `A` extension: atomic memory access
** `LR`/`SC` fully supported
** AMONone PMA on all of memory (AMOs are decoded but unconditionally trigger access fault without attempting memory access)
* Some nonstandard M-mode CSRs for interrupt control etc
