SPI 光谱仪是伽马射线天文仪器之一，将安装在欧洲航天局计划于 2001 年发射的 ESA INTEGRAL 卫星上。数字前端电子子系统 (DFEE) 负责对锗 (Ge) 探测器和德国铋 (BGO) 反符合屏蔽产生的各种测量结果进行实时数据处理。 DFEE的中央处理单元在数字ASIC电路中实现，它提供各种时间信号的实时关联，获取关联的能量测量，并对各种类型的物理事件进行分类。论文给出了DFEE的系统约束、ASIC电路的架构、技术要求以及测试和集成的策略。重点是高级语言开发和仿真、自动电路综合方法以及性能评估。
The SPI spectrometer is one of the gamma-ray astronomy instruments that will be installed on the ESA INTEGRAL satellite intended to be launched in 2001 by the European Space Agency. The Digital Front-End Electronics sub-system (DFEE) is in charge of the real time data processing of the various measurements produced by the germanium (Ge) detectors and the Bismuth Germanate (BGO) anti-coincidence shield. The central processing unit of the DFEE is implemented in a digital ASIC circuit, which provides the real time association of the various time signals, acquires the associated energy measurements, and classifies the various types of physics events. The paper gives the system constraints of the DFEE, the architecture of the ASIC circuit, the technology requirements, and the strategy for test and integration. Emphasis is given to the high level language development and simulation, the automatic circuit synthesis approach, and the performance estimation.
