Using FPGAs with Embedded Processors for Complete Hardware and Software Systems

摘要

Field Programmable Gate Arrays (FPGAs) with embedded processors allow the instrumentation designer to field a system that tightly couples high speed (>500MHz) digital logic to a Control Systems-friendly software platform (i.e. Linux, VxWorks, EPICs). This technology merges CPU and I/O functions onto a single board allowing greater flexibility in physical form factor, power requirements, and data management. Without being constrained by a bus standard, hardware and software can join in a malleable design template. LBNL is currently using this technique to design a control system module for ALS booster top off operation and has completed designs for PEP-II transverse feedback electronics and ALS bunch cleaning. This presentation will include a hands-on demonstration of an FPGA evaluation board running a simplified example of a control system interface.
