标题[理工] [计组]-清大93 page计算
时间Sun Jan 10 15:42:11 2010
Consider a logical address of 2048 pages of 1024 words (4byte) each,
mapped onto a physical of 64 frames. Assume the smallest memory
allocation unit is one byte
a. How many bits in the logical and physical address
b. one-level page table is used, how many bytes are required by PT
c. two-level PT is used, and first level table has 32 entries,
what is the minimal amount of memory required by PT.
可以帮我算一下吗?(以及列式)
另外题目有点看不懂，是说总共2048个page?
每个page有1024个word? 那(4byte)又是指什麽?
谢谢
