What distinguishes data memory from register memory in a computer?
Please answer all the following questions. 1. In a hypothetical computer, the processor has four registers: an 8-bit Program Counter (PC), a 16-bit Accumulator (AC), a 16-bit Counter (CTR), and a 12-bit Pointer (PTR). The memory is divided into words each of which is 16-bit long. Each word can hold either an instruction or a piece of data. For each instruction X, the four most significant bits (denoted by X15-12) represent an opcode. The rest of the instruction (denoted by X11-0) can be either an address or a value of an operand. The table below explains some of the instructions supported by the processor. Opcode (binary) 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 Operation Load AC from a memory location whose address is X11-0. Store AC into a memory location whose address is X11-0. Add to AC the contents of a memory location whose address is the value of PTR. The result is saved to AC. 1100 Subtract from AC the contents of a memory location whose address is the value…
Assume a CPU with a fixed 32-bit instruction length has the following instruction format:opcode mode [operand1] [operand2] [operand3]The mode encodes the number of operands and each operand’s mode. For instance, one mode indicates three registers, another indicates two registers and an immediate datum, another indicates a main memory reference, etc. Assume there are 94 instructions and 22 modes. Answer the following.a. One mode indicates three registers. How many registers can be referenced in this mode?b. One mode indicates two registers and an immediate datum in two’s complement. Assuming there are 32 registers, what is the largest immediate datum that can be referenced?c. One mode has a destination register and a source memory address (an unsignednumber). Assuming 16 registers, what is the largest memory reference available?d. One mode has two memory addresses, both using base displacement. In both, the basesare stored in index registers and the displacements are specified in the…
