5G NR is a central application direction for the Venus communication–AI architecture. This page separates the processing flow, the original hardware demonstrations and the cases measured in ACE-Echo 1.0.
From synchronization to system information
- 01
Find the cell
Detect synchronization signals and determine the physical cell identity. PSS and SSS contribute to the NR cell-identity calculation.
- 02
Decode the broadcast
Process PBCH and its reference signals to recover the broadcast payload and MIB information.
- 03
Acquire system information
Use control-channel scheduling to locate the shared-channel transmission carrying system information such as SIB1.
This is a conceptual flow, not a fixed latency guarantee. Synchronization accuracy, acquisition time and decoding success depend on the waveform, channel, configuration and implementation. See 3GPP TS 38.211, release 16 for physical signals and TS 38.331 for broadcast/system-information definitions.
What the project has demonstrated
| Evidence | What it describes |
|---|---|
| January 2025 FPGA demonstration | A historical UVP PBCH/MIB experiment on an evaluation board |
| First-generation silicon | Chip bring-up and real-signal NR cell search, recorded in the 2026 project review |
| ACE-Echo 1.0 regression | nrPBCH and nrPDCCH among eight software/RTL timing-comparison DAGs |
The first-silicon milestone does not certify complete PBCH/MIB/SIB1 operation, long-duration stability or end-to-end throughput. Likewise, matching known simulator/RTL output bits does not establish an independent algorithm reference.
Develop an NR application
Begin with the small installation smoke, then inspect the paired radio workload sources and their required inputs. Fix the input matrix and expected outputs before comparing implementations. Use the programming model to split work into tasks and the validation report to interpret timing results.
