RCU status report

• Focus on
• Status of the DCS board firmware and low level
  software.
• Status of the RCU actel firmware

3
DCS board firmware status

• Firmware v2.2
• Based on TRD DCS FW v011
• Memory mapped interface.
• RCU Flash Interface.
• Read, write, erase sector and erase complete
  flash.
• Uses same Linux driver/software as existent
  solution.
• 50 kB/s bandwidth from DCS-Linux to RCU-flash
  when writing. (Reading is faster)
• Selectmap Interface.
• Direct Control from Linux
• SW to FW Memory compressing included (2x16, 3x10,
  4x8bit)
• Handling of RCU interrupt

RCU Actel Status

• Version 1.1 is finished and supports
• DCS memory mapped mode, direct selectmap mode and
  flash mode.
• Read/write single frames on Xilinx using DCS
  messagebuffer
• Scrubbing single and continous from rcu-flash
• Visit our Wiki for Firmware programming file and
  documentation
• http//www.ift.uib.no/kjeks/wiki/

Todo list

• DCS
• Integrate SW interrupt handling (tested and found
  working)
• Selectmap kernel module and software.
• Integrate ADC readout
• Include relevant SW from Tobias Krawutsche
• More irradation tolerant FW design (triple
  redundancy...)

• RCU Actel
• Include frame by frame readback and verification
  (Conceptually design done)
• More irradation tolerant FW design (triple
  redundancy...)
• Challenge Deal with the limited space of the
  Actel while also including more irradation
  tolerant design techniques.

But... ALL important functions are ready
and working
