6.1 CLA PSA

The Parallel Signature Analysis (PSA) ensures the integrity of code execution on Control Law Accelerator (CLA). CLA-PSA logic allows computing the signature of Program Address Bus (PAB) and Data Write Data Bus (DWDB) of the CLA. The golden signature can be either computed offline or during the initialization phase of the application. This can subsequently be compared with the signature computed during execution to ensure the correctness of the executed code.
