Suppose there were two "central" processing units attached to the same memory and executing different programs. Furthermore, suppose that one of these processors needs to add one to the contents of a memory cell at roughly the same time that the other needs to subtract one from the same cell. (The net effect should be that the cell ends up with the same value with which it started.)
a. Describe a sequence in which these activities would result in the cell ending up with a value one less than its starting value.
b. Describe a sequence in which these activities would result in the cell ending up with a value one greater than its starting value.
(Asterisked problems are associated with optional sections.)
