Transaction Level Control for Application Execution on the SegBus Platform

We define here a simple, low level control procedure definition, to support application implementation on a particular multiprocessor platform, namely the "SegBus" segmented bus. The approach considers communication as data package transactions from one device to another. It takes into consideration the platform characteristics and requires details of application partitioning and mapping on platform resources. The dependency between operations are extracted from a SDF-like representation, and the actual control code is produced as "application-dependent" VHDL code, grouped in so-called snippets, application and platform instance dependent. The obtained code is inserted in a specific section of a (segment or central level) arbiter. We illustrate the application of our approach on a small implementation example.
