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
Describe the function of the instruction set of a CPU?
They tell the CPU where to find the data, when to read it, and what to do with it.
Temporarily holds data and instruction as the CPU processes them?
Random Access
What is the next step of CPU instruction?
The next step of CPU instruction typically involves the execution phase, where the CPU carries out the operation defined by the instruction. This follows the instruction fetch and decode stages, where the instruction is retrieved from memory and translated into a form the CPU can understand. During execution, the CPU performs arithmetic, logic, or control operations, often interacting with registers and memory to process data. After execution, the CPU will move to the next instruction in sequence, continuing the cycle.
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 situation in which the Cpu needs the result of previous instruction to process another one?
data dependency
What is a command to the CPU to perform one processing function on one or two data inputs?
An instruction is a command to the CPU to perform one processing function on one or two data inputs.
What are multi vector and SIMD computers?
(Single instruction, Multiple Data) A process that allows the CPU to execute a single instruction simultaneously on multiple peices of data, rather than by repetitive looping.
A where does CPU fetch the data and instruction from?
The CPU fetches data and instructions from the computer's memory, primarily the Random Access Memory (RAM). When a program is executed, its instructions and the data it requires are loaded from storage (like a hard drive or SSD) into RAM, where the CPU can quickly access them. The CPU uses the memory address provided by the program counter to retrieve the relevant instructions and data.
Which two additional steps are required in the instruction execution when a memory operand is used?
When a memory operand is used in instruction execution, two additional steps are required: first, the effective address must be calculated to locate the data in memory. Second, the data at that calculated address must be fetched from memory into a register or the CPU for processing before executing the instruction. These steps are essential to ensure that the CPU has the correct data to operate on.
Role of instruction pointer in 8086?
Its role is to point to the next instruction to be executed in the CPU. It always points to the next instruction to be executed in the CPU
What is an example of an instruction set that might be found on a CPU?
An example of an instruction set found on a CPU is the x86 instruction set, which is widely used in Intel and AMD processors. This instruction set includes a variety of operations such as arithmetic calculations, data movement, and control flow instructions, allowing the CPU to perform complex tasks. Another example is the ARM instruction set, commonly used in mobile devices, which is designed for efficiency and lower power consumption.
