1. Update on FPGA/IOC applications and RTEMS developments at the APS W. Eric Norum 2007-10-13

2. 2 Coldfire/FPGA systems Deployed –PAR RF AWG “EPICS Appliance” – all code,.dbd,.db, st.cmd in flash Last reboot – 2006-05-25 –Monopulse beam-position monitors >500 PVs Multiple 256k-point waveforms Reboot without affecting fast feedback operation –Bunch purity measurement Measure arrival time of CFD pulse with ~500ps resolution Two 7776-bin 32-bit histograms in FPGA (6 bins/RF bucket) –P0 feedback Testing/development –Booster tune measurement –Smart power supply controls

3. 3 Arcturus μCDIMM ColdFire 5282 module Motorola/FreeScale ColdFire 5282 processor (64 or 80 MHz) 16 Megabyte SDRAM (32-bit data path) 4 Megabyte flash memory (RTEMS/EPICS/IOC) 1/2 Megabyte on-chip flash (bootstrap) SO-DIMM form factor ~$200 in small quantities, $120 each for orders of 500 or more.

4. 4 Arcturus μCDIMM ColdFire 5282 module 10/100 Mb/s Ethernet (10/100 BaseT) 3 serial ports (2 RS-232, 1 LVTTL) I 2 C and SPI CAN support 8-channel, 10-bit ADC A24/D16 external bus 5 interrupt request lines 16 general-purpose I/O lines

5. 5 Arcturus μCDIMM ColdFire 5282 module Example of other uses – DESY DIN-rail IOC

6. 6 APS μCDIMM ColdFire 5282 EPICS Environment All APS applications of the ColdFire μCDIMM use it with an FPGA devLib support make FPGA components look like VME-bus modules Same driver code works with vxWorks/VME module and with RTEMS/FPGA component.

7. 7 Coldfire/FPGA integration Altera “System on a Programmable Chip” builder provides drag and drop system configuration FPGA SOPC blocks appear as VME devices to IOC –Standard devLib support –Existing VME drivers (e.g. event receiver) can be used without any modifications!

8. 8 Example FPGA components APS Event Receiver Extended APS Event Receiver (subset of EVR-200) Analog Devices AD7249 serial DAC I/Q phase/amplitude detector + CORDIC 16-channel Proportional+Integral controller 16-channel, 6th-order, IIR filter Serial line monitor (remote IOC reset)

9. 9 EPICS support All ColdFire on-chip devices and FPGA SOPC components are supported in EPICS using ASYN drivers Why ASYN for register-based devices? –Decouples driver from record –Common routines/displays for producing and controlling diagnostic messages –Common INP/OUT field formats

10. 10 RTEMS updates Complete iocClock integration – RTEMS matches vxWorks for time synchronization (NTP, soft event client, hard event client) Proper timezone support (epicsEnvSet TZ "CST6CDT5,M3.2.0,M11.1.0”) tyGSoctal driver (Greensprings Octal UART Industry Pack Module) –Complete termios support –Complete set of IOC shell commands Memory pool free space available as PV “spy” command Hooks in startup code before/after network configuration –Example – BSP100 module sets network information and path to startup script based on front-panel switch settings. One-spare fits all! Better support for ‘global environment variables’ on MOTLOAD processors Available in CVS snapshots. R3.14.10 coming soon?
