Two major trends can be observed in a modern system-on- chip design: first a growing trend in system complexity, which results in a sharp increase of communication traffic on the on-chip communication bus architectures. The second in technology scaling indicates that the wires are getting thinner and results in an increment of wire delay and power consumption. These, in turn, result in the degradation...
In this paper, we present a bus and memory architectures co-synthesis technique. The co-synthesis problem is formulated as an optimization problem, where scheduling, allocation, and binding of tasks are done simultaneously in order to optimize the bus widths, the number of buses, and the memory sizes. As a main contribution, bus and memory architectures are optimized simultaneously by allocating different...
A major trend in a modern system-on-chip design is a growing system complexity, which results in a sharp increase of communication traffic on the on-chip communication bus architectures. In a real-time embedded system, task arrival rate, inter-task arrival time, and data size to be transferred are not uniform over time. This is due to the partial re-configuration of an embedded system to cope with...
This paper presents an energy efficient on-chip communication synthesis for shared bus based architecture. An assumption for the synthesis is that a system has already been partitioned and mapped onto the appropriate modules of a SoC so that size of data to be transferred at each time by an on-chip module is fixed. The problem of communication synthesis is modeled in NLP (nonlinear programming), which...
