Coa Unit 4 1 Input Output Organisation Pdf The input and output instructions transfer data among processor registers and input or output terminals. the push and pop instructions transfer data between processor registers and a memory stack. different computers use different mnemonics symbols for differentiate the addressing modes. Unit 2 coa the document discusses computer architecture focusing on instruction codes, operation codes, and the organization of stored programs. it explains the structure of instruction formats, types of instructions, the role of registers, and the timing and control unit in executing instructions.
Coa Unit 3 Pdf Usb Input Output Central processing unit the part of the computer that performs the bulk of data processing operations is called the central processing unit (cpu) and is the central component of a digital computer. Input and output instructions are needed for transferring information to and from ac register, for checking the flag bits, and for controlling the interrupt facility. input output instructions have an operation code 1111 and are recognized by the control when d7 = 1 and i = 1. the remaining bits of the instruction specify the particular. Input output instructions: input and output instructions are needed for transferring information to and from ac register, for checking the flag bits, and for controlling the interrupt facility. • after the information has been fed into the computer via the input device, the information is processed by the central processing unit, also known as the cpu.
