Audio Reach | Audio Weaver |
Developed for power constrained mobile products. Single use case. | Developed for high-performance automotive audio. Multiple concurrent use cases. |
Variable processing load. | Constant / deterministic real-time load |
Must keep cores loaded < 70% | Can load cores to 90% |
Separate AMS framework needed for low latency support. End-to-end digital latency of 3 x block size. | Native low-latency support. End-to-end digital latency of 2 x block size. |
TDM ports aligned within 12 samples | TDM ports aligned within 1 sample |
SysMon does not provide actionable information to fully load the system. | Easy to understand profiling. Per module, per thread, and per core. Show average and peak CPU load. |
Only supports Hexagon DSPs; no Arm. | Supports all cores including Arm. |
QXDM is a poor fit for real-time debugging. | Includes integrated visual debugging tools and legacy QXDM. |
Numerous side effects. Many features can only be supported by Qualcomm. | Architecture is fully documented and information is publicly available. |

We should include a full-featured block diagram which shows how to implement a complete automotive system in Audio Weaver. We could have placeholders for some functions, like RNC and Telephony, but it should be multicore and highlight best practices for designing systems.
