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.

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!

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 ProportionalIntegral controller
• 16-channel, 6th-order, IIR filter
• Serial line monitor (remote IOC reset)

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

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?
