Memory ECC scrubber
Maturity plannedTargets FPGA + ASICDifficulty EasyPriority 2
Background patrol scrubber that reads memory regions at a programmed rate, corrects single-bit errors by write-back and logs uncorrectable addresses.
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 |
| m_axi | out | valid-qualified bus | 256 | AXI4 master port (AW/W/AR channels) |
Standards
No external standard applies.
