cpu registers and their functions

Functions of this unit are − It is responsible for controlling the transfer of data and instructions among other units of a computer. Depending upon the value of result after any arithmetic and logical operation the flag bits become set (1) or reset (0). The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output. Registers contain the address of the memory location where the data is to be stored. CPU uses these registers to handle the process of execution effectively and efficiently. The computer needs processor registers for manipulating data and a register for holding a memory address. The size of the register is very important for modern controllers. Registers are small, fast memory storage facilities inside the CPU. The register consists of a group of flip-flops and gates. To control instructions and data flow to and from other parts of the computer, the CPU relies heavily on a chip set, which is a group of microchips located on the motherboard. Match. They include a number of general purpose registers that the programmer can use to hold intermediate results whilst working through a calculation or algorithm. I/O and peripheral control (such as serial ports or general-purpose IOs) ... Central Processing unit (CPU) 14 Terms. CPU or Central processing unit is the brain of the computer system. Test. A register is like a variable, except that there are a fixed number of registers. The 32-bit instruction pointer register and the 32-bit flags register combined are considered as the control registers. This design is still used in most computers produced today. A register is a high speed storage area inside a central processing unit. A Special Function Register (or Special Purpose Register, or simply Special Register) is a register within a microprocessor, which controls or monitors various aspects of the microprocessor's function.Depending on the processor architecture, this can include, but is not limited to: . The Intel 8088, released July 1, 1979, is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), and is notable as the processor used in the original IBM PC design. Some of the primary components of a CPU, also known as a microprocessor, are the arithmetic logic unit (ALU), the control unit and the registers. The decode function is used for interpreting the instruction. An n-bit register has a group of n flip-flops and is capable of storing binary information of n-bits.. A register consists of a group of flip-flops and gates. A computer is a set of systems with its hardware components which are connected using different types of computer ports. Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only [3] It is capable of many complex mathematical functions, for example sine, cosine and floating point division. It holds the the memory address of the data being referenced. It carries out three different functions: fetch, decode and execute. This memory is vital for moving data in and out of the main memory and to process the data. It obtains the instructions from the memory, interprets them, and directs the operation of the computer. Start studying Registers and their function. Flashcards. mstric6. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters).Some instructions specify registers as part of the instruction.
