Question # 01 10 Marks
Consider the below given table consisting of assembly instructions belonging to different processors.
|JPL R5, ||Falcon - A|
|STS R7, R2 (100)||Falcon - E|
|STACC R4, 36||Modified EAGLE|
|SHIFTL R5, R2, 7||FALCON - A|
Write machine code (in the hexadecimal representation) and behavioral RTL description for each instruction given in table.
Question # 02 10 Marks
Consider the below given tables belonging to Modified EAGLE architecture.
• Table 1 shows the contents of registers R1, R2 and memory labels A, B, C. The contents of memory labels are memory addresses.
Table 1: Contents in Registers and Memory labels
• Table 2 represents byte- aligned memory map and shows the value stored at each memory address.
|Memory Address||Memory Contents||Memory Address||Memory Contents|
Table 2: Contents at different memory addresses
• Table 3 contains the instructions of an assembly program for Modified EAGLE. You are required to complete Table 3 by writing the values of destination operand, 16-bit address bus and 16-bit data bus after each instruction is executed.
Write the complete steps for calculating the values of Destination Operand, Data Bus & Address Bus after the execution of each instruction.
|Instruction||Contents stored in Destination Operand||Data Bus||Address Bus||Calculation Steps|
