Memory size Q: B. A computer uses a memory with 8 bits in each addressable word. It has the following registers: PC and AR, which are used for addresses only and AC. DR. IR. IR (32 bits each). A memory-reference instruction consists of 32 bits: an 8-bit operation- code and an address (in the next three bytes). What is the size of the memory for this computer?? _____________________________________ What is the size of the memory if the addressable memoryy word is increased to 16 bits ____________________________________ By how many addresses AR and PC are incremented to point to the next instruction, if the memory word is 8 bits Address step By how many addresses AR instruction, if the memory word is Address step How many opcodes can be generated by this computer? opcodes Memory size and PC? are incremented to point to the next 16 bits

Explanation / Answer

1. 28

2. 2 bytes

4. computer uses 65,536 words with 8 bits in each word

5. 4 bit encoded represent 16 different operations so, 8 bit encoded reprent 64 different operations
