Suppose you need to process a list of 31,000 integers contained in Pep/8 memory

Question

Suppose you need to process a list of 31,000 integers contained in Pep/8 memory at one
integer per word. You estimate that 20% of the instructions in a typical program are
unary instructions. What is the maximum number of instructions you can expect to be
able to use in the program that processes the data? Keep in mind that your applications
program must share memory with the operating system and with your data.

(a) What company manufactured the computer you are using? (b)How many bytes
are in its main memory? (c)How many registers are in its CPU? How many bits are in
each register? (d)How many bits are contained in a single instruction? (e)How many
bits of the instruction are reserved for the opcode?

Explanation / Answer

maximum number of instructions you can expect to be will be:

31000-(20/100)*31000 = 31000-6200 = 24800.
