Does ADSP-CM40x feature a Data Cache?


The 16KB cache inside ADSP-CM40x is designed to accelerate execution from flash
memory, which means that it is meant to act as a Code Cache. Because the Cache
is connected to D-Code bus of Cortex (along with I Code bus), it can still
cache raw read-only data for user. However, this will hit performance and is
not recommended.
