Control-flow integrity monitor
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 3
Trace-fed monitor that checks call and return pairing and indirect branch targets against a policy, outside the monitored core.
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 | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| trace_in | in | valid-qualified bus | 128 |
