Columnar format decoder
Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 3
Decoder for Parquet and ORC encodings (RLE, bit-packing, dictionary, delta) feeding decoded column vectors to analytics engines.
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 |
| page_in | in | AXI4-Stream | 256 | |
| col_out | out | AXI4-Stream | 512 |
Standards
- Apache Parquet Format 2.10
