Konferensbidrag (refereegranskat)abstract
- We propose (sigma, rho)-based flow regulation as a design instrument for System-on-Chip (SoC) architects to control quality-of-service and achieve cost-effective communication, where sigma bounds the traffic burstiness and rho the traffic rate. This regulation changes the burstiness and timing of traffic flows, and can be used to decrease delay and reduce buffer requirements in the SoC infrastructure. In this paper, we define and analyze the regulation spectrum, which bounds the upper and lower limits of regulation. Experiments on a Network-on-Chip (NoC) with guaranteed service demonstrate the benefits of regulation We conclude that flow regulation may exert significant positive impact on communication performance and buffer requirements.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A main challenge for Network-on-Chip (NoC) design isto select a network architecture that suits a particular application.NNSE enables to analyze the performance impactof NoC configuration parameters. It allows one to(1) configure a network with respect to topology, flow controland routing algorithm etc.; (2) configure various regularand application specific traffic patterns; (3) evaluatethe network with the traffic patterns in terms of latency and throughput.

Definition of Device Level Interface with QoS : Draft Specification
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- 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
