چکیده

Latency-insensitive systems were recently proposed by Carloni et al. for the design of single-clock systems-on-a-chip (SoC’s) using predesigned IP blocks. The goal of this paper is to extend and generalize latency-insensitive systems in such a way that they can be applied to GALS architectures with multiple clocks. In particular, we propose two extensions. The first extension allows each synchronous module to treat its input and output channels in a much more flexible manner (i.e., greater decoupling). As a result, significant improvement in throughput as well as power consumption may be obtained. The second extension generalizes inter-module communication from point-to-point channels to more complex networks of arbitrary topologies.

A Framework for Modeling the Distributed Deployment of Synchronous Designs

Synchronous specifications are appealing in the design of large scale hardware and software systems because of their properties that facilitate verification and synthesis. When the target architecture is a distributed system, implementing a synchronous specification as a synchronous design may be inefficient in terms of both size (memory for software implementations or area for hardware impleme...

Modeling and Analyzing the Implementation of Latency-Insensitive Protocols Using the Polychrony Framework

As Globally Asynchronous and Locally Synchronous (GALS) based System-on-chip (SoC) are gaining importance, a special case of GALS when the global clocking is preserved, but the interconnect delays of multiple clock cycles are to be tolerated has also been proposed, and used. In some cases, such designs, known as Latency-Insensitive Protocol (LIP) based SoC integration are also general enough to...
