The MoPL-3 Grammar

The Map-oriented Programming Language 3 (MoPL-3) is a procedural language to describe applications for reconfigurable accelerators based on the presented data sequencing method. In this appendix a revised version of the MoPL-3 grammar (see See [Bec97] or See [Hen97]) is given. For information on the semantics of MoPL refer to See [Rei99], See [ABH93] and See [ABH94].
