multiprocessor is one where any processor can directly access any memory on the computer, even if it is on a memory bank local to another processor. cache coherence protocol (h) It is possible to implement a shared memory model on a distributed memory multiprocessor by using a (i) A computer with 50 Mbytes of main memory requires G) In a big-endian memory layout, the bits for representing its addresses. byte of a multi-byte word is stored in the memory byte with the lowest address. locality is what is provided by having multi-word cache lines. D A bit in a cache ensures that unmodified cache lines are not written to main memory when evicted from cache
