CAS - CERN Accelerator School: Digital Signal Processing: Sigtuna, Sweden 31 May - 9 Jun 2007

These proceedings present the lectures given at the twenty-first specialized course organized by the CERN Accelerator School (CAS), the topic being Digital Signal Processing. The course was held in Sigtuna, Sweden, from 31 May–9 June 2007. This is the first time this topic has been selected for a specialized course. Taking into account the number of related applications currently in use in accelerators around the world, it was recognized that such a topic should definitively be incorporated into the CAS series of specialized courses. The specific aim of the course was to introduce the participants to the use and programming of Digital Signal Processors (DSPs) and Field Programmable Gate Arrays (FPGAs) evaluation boards. The course consisted of lectures in the mornings covering fundamental background knowledge in mathematics, controls theory, design tools, programming hardware platforms, and implementation details. In the afternoons the students split into two groups with people working in pairs. One group worked on problem solving using a PC-based workstation connected to a DSP evaluation board while the second group performed the same exercise on PCs connected to a FPGA evaluation board. Half-way through the school, those working on DSPs moved to FPGAs and vice versa. The problems to be solved were of increasing difficulty and all of them were directly related to real and practical realizations currently in use in the accelerator field.
