- (d) You are working on a redesign of a simple 16-bit computer which supports at most 64 kilobytes of memory. Currently, memory is word-addressed and all memory accesses load or store a 16-bit value. For example, LDA Ox6502 loads a 16-bit value from address Ox6502 into register A. The change is to support additionally 8-bit accesses, thanks to an expanded machine language (already designed by a colleague) which now supports instructions such as: ; load 16 bits from addr 6502 into A ; load 8 bits from addr 6502 into A LDAW Ox6502 LDAB Ox6502 Outline, at a high level, how you would bring about this change in the CPU design, and mentioning any difficulties you expect to encounter.arrow_forwardCOAL - Computer Organization and Assembly Languagearrow_forwardQuestion 3 (a) Provide a single line of C++ code that will declare an integer pointer variable named x.
