Answer:


Assignment B
 Case Detail:  
A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory
 
 Suppose we have the instruction Load 1000. Given that memory and register R1 contains the values tabulated below:
 
 
Memory Address    Value       
1000    1400       
---       
1100    400       
---       
1200    1000       
---       
1300    1100       
---       
1400    1300     
 
Assuming R1 is implied in the indexed addressing mode, determine the actual value loaded into the accumulator if R1= 200 and fill in the table below:

How many bits are needed for the opcode? How many bits are left for the address part of the instruction?

What is the maximum allowable size for memory?
