of the cache memory. The extrinsic cache behavior can in a event-driven real-time system make it very hard to calculate, or even estimate, the WCET. The rest of this paper will describe some methods how to calculate or make it easier to estimate the WCET by putting restrictions into the...

11 Types of Cache Misses Compulsory misses: happens the first time a memory word is accessed – the misses for an infinite cache Capacity misses: happens because the program touched many other words before re-touching the same word – the misses for a fully-associative cache Conflict misses: h...

The 604's MMUs support up to 4 Petabytes (252) of virtual memory and 4 Gigabytes (232) of physical memory. The MMUs support block address translations, I/O controller interface segments, and page translation of memory segments. Referenced and changed status are maintained by the processor for...
