Register Transfer Notation

digital Digital usually refers to something using discrete digits, often binary digits. Technology and computing Hardware *Digital electronics, electronic circuits which operate using digital signals **Digital camera, which captures and stores digital i ...

synchronous circuit In digital electronics, a synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal. In a sequential digital logic circuit, data are stored in memory devices called flip-fl ...

. An example of high-level RTN is

Verilog Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems. It is most commonly used in the design and verification of digital circuits at the register-transfer level of abstraction. It is also ...

, and a low-level example is

Register Transfer Language In computer science, register transfer language (RTL) is a kind of intermediate representation (IR) that is very close to assembly language, such as that which is used in a compiler. It is used to describe data flow at the register-transfer level ...

. RTN may be written as either abstract or concrete. Abstract RTN is a generic notation which does not have any specific machine implementation details. In contrast, concrete RTN is a notation which does implement specifics of the machine for which it is designed. The possible locations in which transfer of information occurs are: # Memory-location # Processor Register # Registers in I/O device Hardware description languages {{Electronics-stub
