为PHENIX垫腔开发了前端电子模块（FEM）。该模块的控制功能由基于fpga的堆管理器单元在FEM上实现。每个FEM处理2160个前端电子（FEE）通道。数据读取和格式化由FEM上附加的基于fpga的电路完成。三个外部系统通过串行接口提供初始化、定时和数据信息。本文讨论了堆管理器、数据格式化器和串行接口的应用，以满足垫室子系统的特定控制和数据读出需求。讨论了单元功能、接口、时序、数据格式和通信速率。此外，还介绍了子系统的模式控制、串行结构和功能、错误处理、FPGA实现和编程等问题。
A front-end electronics module (FEM) has been developed for the PHENIX Pad Chamber. The module's control functions are performed by the heap manager unit, an FPGA-based circuit on the FEM. Each FEM processes 2160 channels of front-end electronics (FEE). Data readout and formatting are performed by an additional FPGA-based circuit on the FEM. Three external systems provide initialization, timing, and data information via serial interfaces. This paper discusses the application of the heap manager, data formatter, and serial interfaces to meet the specific control and data readout needs of the Pad Chamber Subsystem. Unit functions, interfaces, timing, data format, and communication rates are discussed. In addition, subsystem issues regarding mode control, serial architecture and functions, error handling and FPGA implementation and programming are presented.
