Computer Registers in CPU

The Arithmetic Register (AR) is a 12-bit register used to hold addresses from memory.

The Program Counter is a 12-bit register that holds the address of the next instruction to be executed.

The Local Bus connects the cache to the CPU, facilitating data flow between them.

The Data Register (DR), which is 16 bits in length, holds operands for operations within the CPU.

The Instruction Register (IR) holds instruction codes and is 16 bits in length.

The Temporary Register (TR) is a 16-bit register used to hold temporary data during computation.

The Input Register (INPR) is an 8-bit register used to hold input characters.

The Arithmetic Logic Unit (ALU) performs all arithmetic and logical operations within the CPU using data provided by the registers.

Data flows from the memory/input device to main memory, then to cache, and finally to registers. The CPU's ALU performs operations using the registers, and the data flows back to the registers, cache, and finally to the main memory or an output device.

The Output Register (OUTR) is an 8-bit register that holds output characters.

The Accumulator is called the processor register because it is specifically used by the processor to store intermediate results of arithmetic and logical operations.

A computer register provides temporary storage within the processor.

The memory size of the CPU is 4096 words, with each word being 16 bits.

The Accumulator is a 16-bit register that stores the result of operations, and it is sometimes referred to as the processor register.

The main components of a CPU are Registers, Arithmetic Logic Unit (ALU), Control Unit, and the Local Bus which connects cache to the CPU.
