- There exist some developments on so-called 'synchronous' functional
- languages. In these languages the processing of 'streams' of same-type
- data objects can be described. According objects of different streams
- can be combined, and it is also possible to combine different objets
- of the same stream, for instance if movements in a stream of 'image'
- objects should be detected. The latter is described by using synchronous
- `predecessor' or 'delay' functions, that execute a relative index
- adressing of objects within a stream.
-
- Two languages of this type are 'SIGNAL' and 'LUSTRE' (bibliography
- below). Both are rather similar. Independendly of this languages
- (because I touched this bibliography only later) I have developed a
- synchronous functional language too, that bases on the same idea.
- The objective of my language is the programming of real-time image
- processing systems. Sorry, I don't yet have publications on my
- language, but I am able to deliver a short english description
- on the general principles if required.

- Bibliography:
- -------------
- The first two articles describe the language SIGNAL, the next two
- the language LUSTRE, and the article of Beneviste & Berry concerns
- general aspects.
