Write a program in assembly language that loads register R2 with the word in memory location which is 10 bytes above the address in R0; and loads register R3 with the word in memory location which is 10 bytes below the address in R1. Your program must compare the two numbers in R2 and R3. If number in R2 is less than or equal to the number in R3 it must add the two numbers and save the result in...

A C program has been compiled into the Atmel AVR assembly
language. The following instruction, which is located at address
0x002A, is executed:
i.) What is the binary value contained in the instruction
register (IR) when the instruction is executed?
ii.) What is the hexadecimal value of the program counter (PC)
when the instruction is executed?
iii.) If register r1 = 0x40 and register r2 = 0x02 prior to
executing the instruction, what are the contents of r1 and r2...

Language = Java Create a program to receive book prices until a sentinel value is entered. (Be sure to tell your user what the sentinel value is so they can type it to indicate they are finished with entering input.) After the sentinel value is entered, compute the total book order total and return the following to the user. As book prices are entered, you'll need to have some way to capture the number of books they ordered and the...

The classic five-stage pipeline MIPS architecture is used to
execute the code fragments in this problem. Assume the
followings:
The architecture fully supports forwarding,

register read is performed in the second half of the clock
cycle,
Branches are resolved in the third stage of the pipeline and
the architecture does not utilize any branch prediction
mechanism,
Register R4 is initially 100.
