TISA: Reconfigurable System for Template-Based Stream Computing

For High performance Digital signal process (HP-DSP) system with low-volume market, performance/ watt, flexibility and cost of design are becoming goals pursued by architects. This paper presents a template-based reconfigurable platformTISA-II, where application-specific stream computing system can be constructed fast, efficiently and conveniently. This paper describes the platform in terms of architecture, programming model, a hardware/software co-design flow, and our implementation. Finally, the paper evaluates TISA-II by a real applications HD H.264 encoding. The results are encouraging, TISA-II with 4 computing node achieves 50～100x speedup over embedded programmable processors (C64 DSP, MIPS) and 3x over dedicated stream processor (Storm), while consequently performance per watt that is also greater.
