Implementing and Optimizing of Entire System Toolkit of VLIW DSP Processors for Embedded Sensor-Based Systems

Abstract EN

VLIW DSPs can largely enhance the Instruction-Level Parallelism, providing the capacity to meet the performance and energy efficiency requirement of sensor-based systems.

However, the exploiting of VLIW DSPs in sensor-based domain has imposed a heavy challenge on software toolkit design.

In this paper, we present our methods and experiences to develop system toolkit flows for a VLIW DSP, which is designed dedicated to sensor-based systems.

Our system toolkit includes compiler, assembler, linker, debugger, and simulator.

We have presented our experimental results in the compiler framework by incorporating several state-of-the-art optimization techniques for this VLIW DSP.

The results indicate that our framework can largely enhance the performance and energy consumption against the code generated without it.
