(
A French acronym for Synchronous real -
time Lucid ).
Real -
time
dataflow language for synchronous systems ,
especially
automatic control and signal processing .
A {
Lucid }
subset ,
plus timing operators and user -
defined clocks .
Designed for automatic control applications .
It is based on
the idea that automatic control engineers use to analyse ,
and
specify their systems in terms of functions over sequences
(
sampled signals ).
It thus seems both safe and cost effective
to try to compile directly those descriptions into executable
code .
A lot of work has been done ,
so as to get efficient
compilation ,
and also in formal verification .
The language
has been used in nuclear plant control ,
and will be used in
aircraft control .
