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 X1512 ) represent an opcode. The rest of the instruction (denoted by X110 ) can be either an address or a value of an operand. The table below explains some of the instructions supported by the processor. Given the following program
