Access-controlled security mailbox
Maturity plannedTargets FPGA + ASICDifficulty EasyPriority 2
Lock-and-ownership mailbox with data buffer between host agents and a root of trust, with requester identity checks.
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 |
|---|---|---|---|---|
| ctrl | in/out | AXI4-Lite control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
Standards
No external standard applies.
Basis projects
Permissive open projects the implementation may build on.
- Caliptra RTL (CHIPS Alliance) (Apache-2.0)
