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]] of an [[computer architecture|architecture]].<ref>{{Cite journal |last=Mahani |first=Negin |date=2013-01-16 |title=Making alive register transfer level and transaction level modeling in Ada |journal=ACM SIGAda Ada Letters |volume=32 |issue=2 |pages=9–16|doi=10.1145/2429574.2429576   |url=https://dl.acm.org/doi/abs/10.1145/2429574.2429576  |access-date=September 8, 2024|url-access=subscription }}</ref> Academic papers and textbooks often use a form of RTL as an architecture-neutral assembly language. '''RTL''' is used as the name of a specific intermediate representation in several compilers, including the [[GNU Compiler Collection]] (GCC), Zephyr, and the European compiler projects CerCo and [[CompCert]].
