Question: Explain the current program state of an ARM7TDMI if the CPSR had the value 0xF00000D3. ( Chapter 2: The Programmer’s Model. ARM Assembly Language: Fundamentals and Techniques, Second Edition Book by William Hohl)

1. (10 pts) On the ARM7TDMI, let the SP register hold 0x814C and memory hold the following (all values in hexadecimal) at the start of part (a) and the start of part (b). address contents 8144 12121212 8148 33334444 814C ABABABAB 8150 50005000 8154 67896789 (a) After executing the following instruction POP fr3, r4, what are the contents of r3, r4, and SP?

Write an assembly language program for ARM7TDMI to count the number of 0's and 1's in 01639. Store the number of 0's in register R0 and the number of 1's in register R1. Consider Number either 32 bit or 16 bit.

Write a routine for the ARM7TDMI that reverses the bits in a register, so that a register containing d31d30d29...d1d0 now contains d0d1...d29d30d31. Compare this to the instruction RBIT on the Cortex-M4.

Engineering; Computer Science; Computer Science questions and answers; On the ARM7TDMI, if the stack pointer (SP) holds the address 0x1000 and you executed the following instruction: STMDB SP!, {LR, r3, r9, r7, r2} what addresses now hold the values previously held in: a.

Which mode on an ARM7TDMI can assist in supporting operating systems, especially for supporting virtual memory systems? 9. How do you enable interrupts on the ARM7TDMI? 10. How many stages does the ARM7TDMI pipeline have? Name them. 11. Suppose that the Program Counter, register rl5, contained the hex value 0x8000. From what address would an ...

Explain the current program state of an ARM7TDMI if the CPSR had the value 0xF00000D3. Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

5. Which bits of the ARM7TDMI status registers contain the flags? Which register on the Cortex-M4 holds the status flags? 6. If an ARM7TDMI processor encounters an undefined instruction, from what address will it begin fetching instructions after it changes to Undefined mode? What about a reset? 7. What is the purpose of FIQ mode?
