3.5.1.24.4 SoC Profiler
(Ask a Question)SmartHLS™ includes a lightweight profiler that allows the measurement of the amount of time spent transferring data between the CPU and the generated hardware modules. Ideally we want to have a high computation-to-communication ratio to maximize the use of a hardware accelerator. In other words, minimize the amount of communication (time sending and receiving data), and maximize the amount of time the hardware modules are actively processing data.
The SmartHLS soc profiler allows a breakdown analysis of the application runtime to identify potential optimizations. For example, depending on the application, sometimes we can run concurrently multiple hardware modules instead of a sequential execution. Another example is we can try to overlap communication and computation time to make more efficient use of hardware resources.
