摘要：FPGA based designed card provide several advantages over custom designed IC based cards such as reduced cost, reduction in components, reduction in size ,easily coded . It is flexible because its parameters can be changed at any time by reprogramming the device. FPGA based VME Bus compatible four channels ADC card is used to acquire the Beam Position Indicator (BPI) electrode data. This card is having on-board 4-channel ADC (with signal conditioning electronics) and 8-channel Opto-coupler inputs. Additionally there is a memory available on-board to save digitized voltages. In all, the system is VME based so this card is a VME slave board where VME CPU card will be able to control the card and read the calculated beam position whenever it is available in memory.
