Definition of Device Level Interface with QoS: Draft Specification
2007 (English)Report (Other academic)
The extensions to standard IP communication interfaces proposed in SPRINT WP3document D3.1 are defined.
Flow identification signals are added to the DLI signal level interface so transactionscan indicate the services they require. These services are specified as Contracts thatdefine the flow characteristics required for correct operation. These characteristics arethe main input to an analysis method to validate that a SoC design achieves its performance targets.
DLI-Guard units are defined that enforce Contracts by regulating an IP module’s identified flows. Monitoring of flow characteristics, such as latency, is also optionally provided. A configuration API for DLI-Guards is outlined together with example code toillustrate its use.
This specification is successfully applied to AMBA AXI, the prime example DLI
