Answer #1

Convert the following AVR Assembly Language Instruction to machine code:

and r31, r0

Answer: 0010000111110000 (Binary)

Description:

• Instruction: and - Logical AND

• Instruction Format: and Rd, Rr

The above instruction performs the Logical AND between Rd and Rr register and place the result in Rd register. Here, 0 ≤ r ≤ 31 and 0 ≤ d ≤ 31.

Rd ← Rd • Rr or Rd ← Rd AND   Rr

• 16-bit opcode:  and r31, r0

• Here, opcode for and is: 001000 (bits 15 - 10)

• Register Rr = r0. So, r rrrr is 00000 (bit 9 and bits 3 - 0)

• Register Rd = r31. So, d dddd is 11111 (bits 8 - 4)

• So, 16-bit Binary machine code is: 0010000111110000.

Hexadecimal: 0x21F0

Write an ARM assembly language program that counts the number of 1’s for any value in R0. The program must assemble/compile in KEIL and must be able to run in the KEIL simulator. Generally, R0 may contain any value, but for purpose of this exercise, you may move 0x2345ABCD into R0. The number in R0 does not need be preserved. You may use any other registers as you need. The result, total count of 1’s in R0, should be in...
