- Implemented tests for the deterministic baseline JPEG reference model in , covering encoding, decoding, quality scaling, and error handling. - Created to ensure synchronization between RTL and C register constants for JPEG. - Updated to reflect changes in the number of APB interfaces and IRQ mappings, ensuring the topology generates correct bindings.
