DIRECT MAPPING
PROBLEM 1
A block direct mapping cache has line/slot that contains 4 words of data. The cache size is 16k line. Main memory contains 16k blocks of 128 byte each.
a) What is the total capacity of main memory in Mbytes?
b) How many bits are used for main memory address?
c) How many bits for words in cache?
d) How many bits for lines/slots in cache?
e) Draw the format for main memory address by specifying the size of tag, line/slot and word?
