![Assembly:
1. A word addressable computer has 1GB of
memory and the word size is 64 bits.
Assuming there are 80 control lines and 40
interrupt lines. How many lines are there in
the system bus?
2. What is the benefit of using multiple- bus
architecture compared to a single bus
architecture ?
3. Suppose we are designing an instruction set
architecture with 30- bit instructions that
support 46 different operations . Each
instruction contains both source and
destination registers and an immediate
operand whose value can be in the range
plus/minus 32 * K . Draw the instruction
format.
4. Consider the following piece of assembly
code:
MOV BX, 77FFH
MOV AX900OH
DEC AL
MOV BH, 88H BL
CMP BX, AX
What is the value of AX, BX, the carry flag (CF),
and the sign flag (SF) after executing the above](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9e51ba8a-6fc0-4607-86b6-76384dcd79bb%2F423c3e7d-436f-4bdc-9d5f-bbdd28cdd36e%2Fd0jdjz_processed.jpeg&w=3840&q=75)
