Reorder buffer
Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 2
ID-indexed reorder buffer that accepts out-of-order completions and releases them in issue order, with allocation and credit tracking.
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 |
|---|---|---|---|---|
| s_in | in | valid-qualified bus | 72 | |
| m_out | out | valid-qualified bus | 64 |
Standards
No external standard applies.
