Parallel code-phase FFT search over Doppler bins for GPS L1 C/A, Galileo E1, BeiDou B1I and GLONASS L1OF signals.
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 |
| samples | in | AXI4-Stream | 8 | |
| hits | out | AXI4-Stream | 64 |
