Complete the AVR assembly language fragment below so that it
performs a division by 4 of the 16-bit unsigned value in registers
r4:r5. (r4 is the most significant byte.)
Homework Answers
Answer:
lsr r4
ror r5
lsr r4
ror r5
Explanation: Division by 4 means, right shifting
twice and making LSL adjustment
Thanks, PLEASE COMMENT if there is any
concern.

Question 4. (continued) (b) Consider a 16-bit binary number stored in AVR registers r15:r14 which the programmer considers to be a two's complement value. (r15 holds the most significant byte, r14 holds the least significant.) Write down a sequence of AVR assembly language instructions which perform each of the following operations The result should end up in r15:r14. Other registers can be used freely if required i) Sets r15:r14 to the constant value-1 (2 marks)...

Write an 8086-family assembly language procedure (code fragment) that would fill the first part of a complete segment of memory (assume the segment is the data segment) with zeros (up to a certain offset within the segment), and the rest of the segment with ones. The code will fill the locations within the segment, up to the offset given in BX, with all 0s. Once the offset reaches the value in BX (inclusive), fill the rest of the locations form...
