  • The Microprogrammed Control Unit
    The Microprogrammed Control Unit Up to this point, we have studied: 1. The microoperation sequence associated with each assembly language instruction 2. The control signals associated with those microoperations. 3. The use of combinational logic in the form of a signal generation tree to generate these control signals. We now consider another option for generating the control signals. This is the microprogramming option, in which representations of the control signals are stored in a micro–memory and read into a MBR (micro–memory buffer register) from whence they are issued. Consider the control signal PC B1. When this is asserted, the contents of the Program Counter are copied onto bus B1. The method of generating this signal has no effect on the action it takes. We have two options for generating each control signal: Hardwired: The signal is output from an AND gate Microprogrammed: The signal is output from a D flip–flop. Survey of Bus Usage and Other Control Signals In order to structure the micro–memory properly, we must tabulate the control signals used and arrange them by use: bus transfer, ALU operation, memory operation, etc. Option Bus 1 Bus 2 Bus 3 ALU Other 0 1 PC B1 1 B2 B3 PC tra1 L / R’ 2 MAR B1 – 1 B2 B3 MAR tra2 A 3 R B1 R B2 B3 R shift C 4 IR B1 MBR B2 B3 IR not READ 5 SP B1 IOD B2 B3 SP add WRITE 6 B3 MBR sub extend 7 B3 IOD and 0 RUN 8 B3 IOA or 9 xor Note the important option 0.

  • 5 Computer Organization
    5 Computer Organization Source: Foundations of Computer Science Cengage Learning 5.1 Objectives After studying this chapter, students should be able to: List the three subsystems of a computer. Describe the role of the central processing unit (CPU). Describe the fetch-decode-execute phases of a cycle. Describe the main memory and its addressing space. Define the input/output subsystem. Understand the interconnection of subsystems. Describe different methods of input/output addressing. Distinguish the two major trends in the design of computers. Understand how computer throughput can be improved using pipelining and parallel processing. 5.2 1 A computer can be divided into three broad categories or subsystem: the central processing unit (CPU), the main memory and the input/output subsystem. 5.3 5-1 CENTRAL PROCESSING UNIT The central processing unit (CPU) performs operations on data. In most architectures it has three parts: an arithmetic logic unit (ALU), a control unit and a set of registers, fast storage locations. 5.4 2 The arithmetic logic unit (ALU) The arithmetic logic unit (ALU) performs logic, shift, and arithmetic operations on data. Logic operations: NOT, AND, OR, and XOR. Shift operations: logic shift operations and arithmetic shift operations Arithmetic operations: arithmetic operations on integers and reals. 5.5 Registers Registers are fast stand-alone storage locations that hold data temporarily. Multiple registers are needed to facilitate the operation of the CPU. Data registers Instruction register Program counter The control unit The control unit controls the operation of each subsystem. Controlling is achieved through signals sent from the control unit to other subsystems.

  • The Central Processing Unit (CPU)
    The Central Processing Unit (CPU) Crash Course Computer Science #7 The Central Processing Unit https://www.youtube.com/watch?v=FZGugFqdr60 Internals ● Arithmetic Logic Unit (ALU) ● Control Unit (CU) ● Registers ● Cache Memory ● The Fetch-Execute Cycle Arithmetic Logic Unit An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic ​ operations. It represents the fundamental building block of the central processing unit ​ (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU). Most of the operations of a CPU are performed by one or more ALUs, which load data from ​ input registers. A register is a small amount of storage available as part of a CPU. The ​ control unit tells the ALU what operation to perform on that data and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory. Control Unit A control unit coordinates how data moves around a cpu. The control unit (CU) is a ​ ​ component of a computer's central processing unit (CPU) that directs operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions. ● The control unit obtains data / instructions from memory ● Interprets / decodes the instructions into commands / signals ● Controls transfer of instructions and data in the CPU ● Coordinates the parts of the CPU Registers In computer architecture, a processor register is a quickly accessible location available ​ to a digital processor's central processing unit (CPU).
