Questions & Answers

Q: What is the purpose of initializing the source address, count, and result registers?

Initializing these registers allows the program to know the memory location of the numbers, the count of numbers in the block, and where to store the sum result.

Q: How does the program calculate the sum of the numbers?

The program adds the numbers byte by byte using the accumulator and a register. It keeps a count to determine when all numbers have been added.

Q: How does the program determine when to stop adding numbers?

The program uses the decrement and jump if not equal to zero instruction on the counter register. It continues adding numbers and decrementing until the counter reaches zero.

Q: How does the program find the average of the numbers?

After adding all the numbers, the sum is stored in the accumulator. The count is stored in another register. The program then divides the sum by the count to find the average.

Summary & Key Takeaways

• The program aims to find the average of a block of n numbers by calculating the sum of the numbers and dividing it by the total count of numbers.

• Important steps in the program include initializing the source address, count, and result registers, adding the numbers, incrementing and decrementing registers, and dividing to find the average.

• The program utilizes flowcharts to visualize the sequence of instructions and uses assembly language instructions specific to the 805.1 microcontroller.
