In digital electronics, especially computing, hardware registers are circuits typically composed of flip-flops, often with many characteristics similar to memory, such as: [citation needed] The ability to read or write multiple bits at a time, and; Using an address to select a particular register in a manner similar to a memory address.
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.
In digital circuit design, register-transfer level (RTL) is a design abstraction which models a synchronous digital circuit in terms of the flow of digital signals between hardware registers, and the logical operations performed on those signals.
Digital electronics is a field of electronics involving the study of digital signals and the ... and the register holds the state. Many digital systems are data flow ...
User-accessible registers can be read or written by machine instructions. The most common division of user-accessible registers is a division into data registers and address registers. Data register s can hold numeric data values such as integers and, in some architectures, floating-point numbers, as well as characters, small bit arrays and
The register window slides by 16 registers when moved, so that each architectural register name can refer to only a small number of registers in the larger array, e.g. architectural register r20 can only refer to physical registers #20, #36, #52, #68, #84, #100, #116, if there are just seven windows in the physical file.
