Write-back Operation
When a cache hit occurs for a data access, the cache line is marked as dirty, meaning that its
contents are not up-to-date with those in the main memory.
11.6.2.2
Write Buffer
The ARM920T incorporates a 16-entry write buffer to avoid stalling the processor when writes to
external memory are performed. When a store occurs, its data, address and other details are
written to the write buffer at high speed. The write buffer then completes the store at the main
memory speed (typically slower than the ARM speed). In parallel, the ARM9TDMI processor can
execute further instructions at full speed.
11.6.2.3
Physical Address Tag RAM (PA TAG RAM)
The ARM920T implements Physical Address Tag RAM (PA TAG RAM) to perform write-backs
from the data cache. The physical address of all the lines held in the data cache is stored in the
PA TAG memory, removing the need for address translation when evicting a line from the cache.
When a line is written into the data cache, the physical address TAG is written into the PA TAG
RAM. If this line has to be written back to the main memory, the PA TAG RAM is read and the
physical address is used by the AMBA ASB interface to perform the write-back.
For a 16-Kbyte DCache, the PA TAG RAM is organized by eight segments with:
• 64 rows per segments
• 26 bits per rows
