COSY communication IP's

TLDR

The Fsprit/OMI‑COSY project establishes transaction‑level interfaces to separate functional IP from architecture and proprietary interfaces. The paper presents the COSY COMMUNICATION IPs, a generic implementation and performance model of system‑level communications, and the COSY‑VCC flow for refining communication from specification to implementation. The IPs implement the extended Kahn Process Network on SoCs, enabling bus‑independent system communications across software and hardware via the VSI Alliance’s Virtual Component Interface.

Abstract

The Fsprit/OMI-COSY project defines transaction-levels to set-up the exchange of IP's in separating function from architecture and body-behavior from proprietary interfaces. These transaction-levels are supported by the “COSY COMMUNICATION IPs” that are presented in this paper. They implement onto Systems-On-Chip the extended Kahn Process Network that is defined in COSY for modeling signal processing applications. We present a generic implementation and performance model of these system-level communications and we illustrate specific implementations. They set system communications across software and hardware boundaries, and achieve bus independence through the Virtual Component Interface of the VSI Alliance. Finally, we describe the COSY-VCC flow that supports communication refinement from specification, to performance estimation, to implementation.
