1. Consider a load-store type machine with the following specifications: - 232 x bytes of memory 32-bit fixed format instructions 32 32-bit general purpose registers (GPR) 3-address register-to-register arithmetic instructions Single address mode for load/store: base + displacement Capable of performing a total of 32 arithmetic operations - For simplicity assume that the machine only performs arithmetic operations plus data transfer operations (i.e. load and store). a) Write the equivalent machine level language corresponding to a C statement of C=A+B b) Give an instruction format for the arithmetic operations. To do this draw a diagram of the instruction format with each field clearly specified. For each field indicate its size, the reason for selected size, and a description of what purpose the field serves. c) Give an instruction format for the load/store operations. To do this draw a diagram of the instruction format with each field clearly specified. For each field indicate its size, the reason for selected size, and a description of what purpose the field serves
