ITCM, DTCM and IRAM access

Hi,

The ITCM and DTCM are used to improve the performance or the access speed (Low latency memory and Unpredictibility of the caches).
Similarly the IRAM also provides the improved speed.
If the system has both IRAM and TCM, then how does the IRAM and TCM access differ (Where does IRAM and TCM connected, is it on system bus)?

Regards,
Malli

IRAM is an Internal RAM. In most of the SOC, we usually have IRAM of size 128KB or 64KB etc... This is usually termed little faster than the SRAM access.
So need to know how this IRAM is different from TCM memory interms of connection and access.
