Recently, most digital systems are designed as GALS (Globally Asynchronous Locally Synchronous) systems.
Several architectures have been proposed as bus architectures for a GALS system : shared bus, segmented bus, ring bus, and so on.
In this study, we propose a ring segmented bus architecture which is a combination of segmented bus and ring bus architecture with the aim of throughput enhancement.
In a segmented bus architecture, segments are connected in series.
By connecting the segments at the end of the bus and constructing the ring bus, it becomes possible to allocate a channel of the bus bidirectionally.
The bus channel is allocated to the shortest path between segments.
We consider a metastable operation caused by asynchronous communication between segments and a burst transfer between segments.
According to the result of simulation, it is shown that the GALS system designed by the proposed method has the desired operations. |
