Shift register. A shift register is a type of digital circuit using a cascade of flip-flops where the output of one flip-flop is connected to the input of the next. They share a single clock signal, which causes the data stored in the system to shift from one location to the next. By connecting the last flip-flop back to the first, the data can ...
Machine code. In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
Harvard architecture. The Harvard architecture is a computer architecture with separate storage [1] and signal pathways for instructions and data. It is often contrasted with the von Neumann architecture, where program instructions and data share the same memory and pathways. This architecture is often used in real-time processing or low-power ...
A Special Function Register (or Special Purpose Register, or simply Special Register) is a register within a microprocessor, which controls or monitors various aspects of the microprocessor's function. Depending on the processor architecture, this can include, but is not limited to: I/O and peripheral control (such as serial ports or general ...
IA-32. IA-32 (short for " Intel Architecture, 32-bit ", commonly called i386[1][2]) [3] is the 32-bit version of the x86 instruction set architecture, designed by Intel and first implemented in the 80386 microprocessor in 1985. IA-32 is the first incarnation of x86 that supports 32-bit computing; [4] as a result, the "IA-32" term may be used as ...
Peephole optimization is an optimization technique performed on a small set of compiler -generated instructions, known as a peephole or window, [1][2] that involves replacing the instructions with a logically equivalent set that has better performance. For example: The term peephole optimization was introduced by William Marshall McKeeman in 1965.
A random-access machine (RAM) is an abstract computational-machine model identical to a multiple-register counter machine with the addition of indirect addressing. At the discretion of instruction from its finite state machine 's TABLE, the machine derives a "target" register's address either (i) directly from the instruction itself, or (ii ...
Processor register. A register-transfer level (RTL) description of a 8-bit register with detailed implementation, showing how 8 bits of data can be stored by using Flip-flops. A processor register is a quickly accessible location available to a computer's processor. [1] Registers usually consist of a small amount of fast storage, although some ...
