2.1.6. External memory data path logic
The external memory data path logic includes a 4-word buffer
and control logic to interface the TIC to the AMBA ASB bus.
Write enables to buffers are generated from the external memory
interface logic. Control signals from the external memory interface
logic block are used to:
drive write data from the memory buffer
on SMDATAOUT bus for the write request from the AMBA ASB master
drive read data to the AMBA ASB interface either
from the buffer or SMDATAIN bus for the read request from the AMBA
ASB master.
