Table 7-23
assuming the core is running at 2 1/2 times the L2 cache frequency. The L2 returns the 128 bits containing
the requested data (critical quad word) first. This data is forwarded to the result register before the full
cache line reloads the L1.
7.6
This section explains the rules of cache and memory-mapped SRAM coherency. The term ‘snoop
transaction’ refers to transactions initiated by the system logic or by I/O traffic, as opposed to e500
core-initiated transactions.
