隨著行動運算裝置的市場需求量逐漸增大，以串流資料為處理對象的應用程式重要性亦隨之提升。為了追求高效能與低耗能的串流資料處理環境，許多嵌入式系統廠商引入數位訊號處理器以追求效能與耗能之間的平衡點，並提供高發展性與成本低廉的發展環境。為了使應用程式的開發者能在這樣的架構下，方便的發展越趨複雜的多媒體程式，友善而穩定的發展平台亦成為一個重要的研究課題。除錯器乃是一個提供程式與發展者交互作用的工具，並且已經被廣泛使用於程式流程的追查與發現錯誤的使用上。在本論文中，我們建構了一個適用於平行架構核心數位訊號處理器的偵錯環境。利用GDB、Eclipse與模擬器的整合，提供程式發展者一個友善而便利的除錯環境。透過更改過的遠端串列通訊協定，我們的系統同時能適用於硬體模擬器。我們並提出一個雙核心偵錯器的架構，能夠處理多個獨立異質的處理單元著偵錯動作。本系統目前為平行架構核心數位訊號處理器初版的偵錯環境。

In nowadays, streaming data application has become more and more important since the portable devices such as PDA, and Smart Phone grew their market. To pursue the optimized balance between high performance and low power consumption for streaming data applications, many embedded systems employ programmable Digital Signal Processor (DSP) as their core component to construct a high-performance, low-power, high-flexibility, and low-cost platform. For such a platform, a developer of applications requires a convenient, friendly, and stable developing environment to deal with more and more complex applications. Debugger, a tool providing interaction between developers and applications, is widely used for tracing codes and hunting bugs in complex applications. In this work, we built a debugging environment on Parallel Architecture Core (PAC) DSP processors. By integrating GNU Debugger (GDB) and PAC DSP Instruction Set Simulator (ISS) with Eclipse Integrated Development Environment (IDE) platform, a convenient and friendly debugging environment for application developers can be provided. Our system also works with hardware ICE environment by following our proposed settings and protocols. We also proposed a dual-core debugging environment platform, which would be an important tool to debug abnormal interaction between independent heterogeneous processing units. Our system is now the initial distribution software framework for PAC DSP debugging environment.
