System-level Scheduling on Instruction Cell Based Reconfigurable Systems

Abstract

This paper presents a new operation chaining reconfigurable scheduling algorithm (CRS) based on list scheduling that maximizes instruction level parallelism available in distributed high performance instruction cell based reconfigurable systems. Unlike other typical scheduling methods, it considers the placement and routing effect, register assignment and advanced operation chaining compilation technique to generate higher performance scheduled code. The effectiveness of this approach is demonstrated here using a recently developed industrial distributed reconfigurable instruction cell based architecture [ 11]. The results show that schedules using this approach achieve equivalent throughput to VLIW architectures but at much lower power consumption.
