There are different techniques to map the macro instruction op-code into control memory address. Formulate a mapping process that will provide eight control words for each of the memory reference operations (7 operations), Register reference instruction and I/O instruction for the computer given in class. Assume that the Control Memory size is 256 words. This was a mapping table for the computer described in the class.
