CHERIoT capability microcontroller core
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 2
RV32E core with CHERI capabilities for memory-safe embedded firmware, including a load filter and hardware revocation support.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ext_irq | in | parallel | 32 | |
| debug_req | in | serial | 1 |
Standards
- CHERIoT ISA
- RISC-V RV32E
Basis projects
Permissive open projects the implementation may build on.
- CHERIoT Ibex (Apache-2.0)
Notes
Instruction and data memory ports (AXI4, AHB or OBI) are master interfaces and are added when the skeleton is promoted; the catalog lists only interrupt and debug pins.
