In computing, a hardware register is a storage area for Digital electronics and particularly Computer hardware including the Central processing unit (CPU) and input/output (I/O) of different kinds. Information is conditionally transferred between registers, sometimes with a functional transform, such as an adder unit. Image File history File links Question_book-3. ... RAM (Random Access Memory) Look up computing in Wiktionary, the free dictionary. ... A digital circuit that acts as a binary clock, hand-wired on a series of breadboards Digital electronics are electronics systems that use digital signals. ... Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware. ... “CPU†redirects here. ... Energy Input: The energy placed into a reaction. ... In electronics, an adder is a device which will perform the addition, S, of two numbers. ...
Typical uses of hardware registers include configuration and start-up of certain features, especially during initialization, buffer storage e.g. video memory for graphics cards, and status reporting such as whether a certain event has occurred in the hardware unit. A graphics/video/display card/board/adapter is a computer component designed to convert the logical representation of visual information into a signal that can be used as input for a display medium. ...
Reading a hardware register involves accessing its memory- or port-address with a "load" or "store" instruction, issued by the processor. Hardware registers are addressed in words, but sometimes only use a few bits of the word read in to, or written out to the register.

Strobe registers are hardware registers which do not store data but are used as a means of triggering an action when they are accessed. They are a means of signaling. In telecommunication, signaling has the following meanings: The use of signals for controlling communications. ...
Processor registers are the top of the memory hierarchy, and provide the fastest way for the system to access data.
Registers are normally measured by the number of bits they can hold, for example, an "8-bit register" or a "32-bit register".
Registers are now usually implemented as a register file, but they have also been implemented using individual flip-flops, high speed core memory, thin film memory, and other ways in various machines.
GDB has four "standard" register names that are available (in expressions) on most machines--whenever they do not conflict with an architecture's canonical mnemonics for registers.
`$fp' is used for a register that contains a pointer to the current stack frame, and `$ps' is used for a register that contains the processor status.
For example, the registers of the 68881 floating point coprocessor are always saved in "extended" (raw) format, but all C programs expect to work with "double" (virtual) format.
