請問 98交大計組第5題
5. (08%) Virtually addressed cache is accessed with a virtual address, while
physically addressed cache is accessed with a physical address.
(i)(2%) Which kind of cache takes the TLB out of normal cache access path,
reducing cache latency?
(ii)(2%) Which kind of cache has aliasing problem?
(iii)(2%) Assume physically addressed cache is used, is it possible to have
TLB miss, but page table and cache hit for a data access?
(iv)(2%) Assume virtually addressed cache is used, is it possible to have TLB
miss, but page table and cache hit for a data access? Please explain your
answer.
請問第一小題是問 用哪種方式mapping的cache嘛？
第二小題什麼是 aliasing problem？
第三跟第四小題考慮 physically addressed cache
跟 virtually addressed cache 這兩種有什麼不同嘛？
謝謝
