1Instruction path length — is a term frequently used to simply describe the number of machine code instructions required to execute a section of a computer program. The total path length for the entire program could be deemed a measure of the algorithms performance on a… …
2Instruction pipeline — Pipelining redirects here. For HTTP pipelining, see HTTP pipelining. Basic five stage pipeline in a RISC machine (IF = Instruction Fetch, ID = Instruction Decode, EX = Execute, MEM = Memory access, WB = Register write back). In the fourth clock… …
3Instruction cycle — An instruction cycle (sometimes called fetch and execute cycle, fetch decode execute cycle, or FDX) is the basic operation cycle of a computer. It is the process by which a computer retrieves a program instruction from its memory, determines what …
4Instruction set simulator — An instruction set simulator (ISS) is a simulation model, usually coded in a high level programming language, which mimics the behavior of a mainframe or microprocessor by reading instructions and maintaining internal variables which represent… …
5Instruction level parallelism — (ILP) is a measure of how many of the operations in a computer program can be performed simultaneously. Consider the following program: 1. e = a + b 2. f = c + d 3. g = e * fOperation 3 depends on the results of operations 1 and 2, so it cannot… …
6Instruction set — An instruction set, or instruction set architecture (ISA), is the part of the computer architecture related to programming, including the native data types, instructions, registers, addressing modes, memory architecture, interrupt and exception… …
7Instruction step — An instruction step is a method of executing a computer program one step at a time to determine how it is functioning. This might be to determine if the correct program flow is being followed in the program during the execution or to see if… …
8Instruction register — In computing, an instruction register is the part of a CPU s control unit that stores the instruction currently being executed. In simple processors each instruction to be executed is loaded into the instruction register which holds it while it… …
9One instruction set computer — Computer science portal A one instruction set computer (OISC), sometimes called an ultimate reduced instruction set computer (URISC), is an abstract machine that uses only one instruction – obviating the need for a machine language opcode …
10Reduced instruction set computer — The acronym RISC (pronounced risk ), for reduced instruction set computing, represents a CPU design strategy emphasizing the insight that simplified instructions which do less may still provide for higher performance if this simplicity can be… …
