WebCache-Inhibited Access (I) When set to 1, indicates a Cache-Inhibited Access. When set to 0 indicates access to address that is cacheable. External caches such as look-aside and directory protocols use this bit to determine their actions. The value of the I bit must be same for all accesses by processors to a given address carried by the Ax ... WebThe MPC750 provides dedicated hardware to provide memory coherency by snooping bus transactions. Figure 3-4 shows the MEl cache coherency protocol, as enforced by the MPC750. Figure 3-4 assumes that the WIM bits for the page or block are set to 001; that is, write-back, caching-not-inhibited, and memory coherency enforced.
WebCaching inhibited pages are used mainly to enforce coherency. — Data cache (D-Cache) write through/copy back pages. • Write tracing.
