Software layer for FPGA-based TESLA cavity control system

The paper describes design and practical realization of software for laboratory purposes to control FPGA-based photonic and electronic equipment. There is presented a universal solution for all relevant devices with FPGA chips and gigabit optical links. The paper describes architecture of the software layers and program solutions of hardware communication based on Internal Interface (II) technology. Such a solution was used for superconducting Cavity Controller and Simulator (SIMCON) for the TESLA experiment in DESY (Hamburg). A number of practical examples of the software solutions for the SIMCON system were given in this paper.

Software for development and communication with FPGA based hardware

This document describes aspects of creating software for communication with hardware, especially with FPGA based systems. Features unique for FPGA systems are compared with features of the traditional electronic systems. There are discussed topics like hardware interface definition, or address space description. Connecting client application is shown with Matlab as an example. Solutions with FPGA and embedded processors are discussed.

DOOCS and MATLAB control environment for FPGA based cavity simulator and controller in TESLA experiment

FPGA based cavity simulator and controller is the next generation control system dedicated for high performance, low latency control algorithm development and implementation. The usage of FPGA technology gives users possibility to create many devices on one board and easy exchange, modify or improve VHDL programmed algorithms. In order to provide the full functionality of the system to the user, and meet the requirements of flexibility and extensibility, an appropriate control software is needed. This paper describes the idea and implementation of control environment dedicated for FPGA based devices. As an example of implementation, two control environments have been implemented; the laboratory software based on Matlab, and the application for accelerator operation using DOOCS environment.

DOOCS and MatLab control environment for FPGA-based cavity simulator and controller in TESLA (SIMCON 2.1) part II: implementation

The paper describes the concept and realization of the DOOCS control software for FPGA-based TESLA cavity controller and simulator (SIMCON). It bases on universal software components, created for laboratory purposes and used in MATLAB based control environment. These modules have been recently adapted to the DOOCS environment to ensure a unified software to hardware communication model. The presented solution can be also used as a general platform for control algorithms development. The proposed interfaces between MATLAB and DOOCS modules allow to check the developed algorithm in the operation environment before implementation in the FPGA. As the examples two systems have been presented.
