Final answer:
The question involves writing a pseudocode for a RISC-style program to identify negative integers in a given list and sum them up. The program uses loops and conditional branching for computation.
Step-by-step explanation:
Writing a RISC-Style Program
Creating a RISC-style program to find the negative integers in a list and calculate their sum involves initializing registers, looping through the data, comparing each number, and conditionally accumulating the total of negatives. Below is a pseudocode outline for such a program:
LOAD R1, 0 ; Initialize sum to 0
LOAD R2, address_of_data
LOAD R3, length_of_data
LOOP:
LOAD R4, [R2] ; Load next number
ADD R2, R2, 1 ; Move to next address
CMP R4, 0 ; Compare number to zero
BRGE NEXT ; If number >= 0, skip addition
ADD R1, R1, R4 ; Add number to sum if negative
NEXT:
SUB R3, R3, 1 ; Decrement loop counter
BRNZ LOOP ; If counter not zero, loop
STORE R1, address_of_sum ; Store the sum of negatives
This program assumes the existence of a block of memory containing integers to process and the use of a simple, made-up assembly-like language to demonstrate RISC principles. The sum of the negative integers found is stored at the specified memory address at the end of the operation.
