Direct Memory Access (DMA) in Computer Architecture For the execution of a computer program, it requires the synchronous working of more than one component of a computer. For example, Processors – providing necessary control information, addresses…etc, buses – to transfer information and data to and from memory to I/O devices…etc. In this, in a control unit with a two-level control store, besides the control memory for microinstructions, a nano-instruction memory is included. In such a control unit, microinstructions do not contain encoded control signals. The operation part of microinstructions contains the address of the word in the nano-instruction memory, which The control memory is programmed to initiate the required sequence of microoperations. A hardwired control, as the name implies, requires changes in the wiring among the various components if the design has to be modified or changed. In the microprogrammed control, any required changes or modifications can be done by updating the microprogram COMPUTER HARDWARE CONFIGURATION MICROPROGRAM EXAMPLE: Two memory units: Main memory, control memory.

Everything you fetch a word from memory, each word is 64-bit. Finally the control bus provides all the control signal such as the signal to indicate whether you are doing a read or a write operation to memory. 4 Control of Registers and Memory Ans: The registers of the computer connected to a common bus system are shown in Fig. 5-4. The control inputs of the registers are LD (load), INR (increment), and CLR (clear).

Say that a sll instruction is located in memory at address 80000180, and an add instruction is located in memory at address 80000184. After the add instruction executes, what value will be in the PC? asked in Computer Architecture by anonymous Virtual memory combines the computer's RAM with temporary space on hard disk. • Types of memory - Memory is just like human brain. It is used to store data and instructions.

When a program starts execution, one or more pages are transferred into main memory and the page table is set to indicate their position. Nano programming: In, most microprogrammed processors, an instruction fetched from memory is interpreted by a micro program stored in a single control memory CM.In some microprogrammed processors, the micro instructions are not directly used by the decoder to generate control signals. They use second control memory called a nano control memory (nCM). Computer Architecture Notes and presentation on (Von Neumann Model, Fetch Execute Cycle) (Input/Output, Memory, Control Unit, ALU and Registers) Von Neumann model of a Computer: There are four functional components that all computers must have: Input/output (I/O) Memory A Control Unit An Arithmetic Logic Unit (ALU) This idea about how computers should be built, called… CONTROL MEMORY  Memory that is a part of the control unit is called Control memory.

Computer Architecture (CA) is one of the most scoring subjects in Competitive Exams.Those who score great in it stands higher on the merit. To help students, we have started a new series call “Computer Awareness for Competitive Exams”.In this post, our team has brought some of the well-compiled MCQ on Computer Architecture asked in Competitive Exams.
