What is a data instruction register?
A Data Instruction Register (DIR) is a component within a computer's CPU that temporarily holds instructions fetched from memory before they are executed. It helps in decoding and executing the instruction by providing the necessary data to the control unit. The DIR plays a crucial role in the instruction cycle, ensuring that the CPU processes commands efficiently. By holding the instruction, it allows for a streamlined flow of data between memory and processing units.
What is the instruction to add the data in register B to the data in accumulator?
add B
What is flynn's taxonomy of parallel architecture?
Flynn's taxonomy is used to categorize computer architectures. Considers the number of processors and the number of data paths incorporated into an architecture. The fours combinations of processors and data path are: SISD( Single instruction, single data stream) MISD( Multiple instructions, single data stream) SIMD (Single instructions, multiple data streams) MIMD( Multiple instructions, multiple data streams)
What is the Flynn classification?
The Flynn classification is a system used to categorize computer architectures based on the number of concurrent instruction streams and data streams they can handle. It includes four main categories: Single Instruction Single Data (SISD), Single Instruction Multiple Data (SIMD), Multiple Instruction Single Data (MISD), and Multiple Instruction Multiple Data (MIMD). This framework helps to analyze and design parallel computing systems by highlighting different processing capabilities. It is named after Michael J. Flynn, who introduced the classification in 1966.
What register points to the next instruction?
actually register holds the data..there are 6 register which are temporary registers..program counter holds the address of next instruction to be fetched..instruction register holds the currently executed data...
What is considered a function of the instruction set for the CPU?
The Functions of the instruction set is to instruct All CPU's with a set of instructions: Tells the CPU where to find data When to read the data What to do with the data. Hope that helps Don
What is instruction cycle with interrupts?
The instruction cycle is the basic operation cycle in a computer. This is what will take in data, process it and execute as required.
PUSH Instruction in 8085 Micro processor?
Push instruction pushes two byte of data on the top of the stack.
Is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received?
"SIMD, which stands for 'single instruction, multiple data,' is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received."(Pg. 434, A+ Guide to Managing and Maintaining Your PC)
How do you calculate instruction address and data address give example?
To calculate an instruction address and a data address, you typically use the base address and an offset. For example, if the base address of a program is 0x1000 and the instruction is located at an offset of 0x0040, the instruction address would be calculated as 0x1000 + 0x0040 = 0x1040. Similarly, if a data item is stored at an offset of 0x0020 from the same base address, the data address would be 0x1000 + 0x0020 = 0x1020.
What is data register?
It is used to hold data or the memory address that contains either the next place of data or an instruction that is to be used .
What is the Flynn's Classification with examples?
First of all as we know the CPU comprises of The Registers,The ALU Unit and the Control Unit.Processing of the data is done in CPU Registers (an area or a memory where processing takes place). M.J.Flynn suggested these architectures for enhancing the computational speed of the computer: 1. Single Instruction Single Data (SISD): Single instruction is performed on a single set of data in a sequential form.Most of our computers today are based on this architecture.Von Neumann fits into this category.Data is executed in a sequential fashion (one by one). 2. Single Instruction Multiple Data (SIMD): Single Instruction is performed on multiple data.A good example is the 'For' loop statement.Over here instruction is the same but the data stream is different. 3. Multiple Instruction Single Data (MISD): Over here N no. of processors are working on different set of instruction on the same set of data.There is no commercial computer of this kind also these are used in Space Shuttle controlling computer (all the buttons you must have noticed in the control center). 4. Multiple Instruction Multiple Data (MIMD): Over here there is an interaction of N no. of processors on a same data stream shared by all processors.Now over here if you have noticed a lot of computers connected to each other and when they perform a task on the same data (data is then shared).If the processing is high it is called Tightly Coupled and Loosely Coupled vice-versa.Most Multiprocessor fit into this category.
