5.) Explain the PUSH and POP operation in stack organization.
6.) Explain the general register organization.
7.) Explain the different instruction formats in the architecture?
8.) Explain the Floating point representation.
9.) What is Associative Memory? How does is facilitate Searching? Explain?
10.) i) How many 128*8 RAM chips & 512*8 ROM Chips are needed to provide memory capacity of 2048 bytes?
ii) How many lines of the address bus must be used to access 2048 bytes of memory? How many of these lines will be common to all chips?
iii) How many lines must be decoded for chip select? Specify the size of the decoders.
iv) List the memory address map.
11.) Write all possible addressing modes; also explain each by taking an appropriate numerical example?
12.) A digital computer has a memory unit of 64k * 16 and a cache memory of 1k words. The cache uses direct mapping with a block size of 4 words.
i) How many bits are there in the tag, index, block & words fields of the address formats.
ii) How many bits are there in each word of cache?
iii) How many blocks can the cache accommodate?
