  16. The real image Espia #1 Espia #2

  17. Image reconstruction in kernel Espia #1 Espia #2

  18. “Very High memory” support High frame rate  many image buffers Physical Memory Implementation in driver • Driver always has 32-bit aux. buffers • If next target frame has 64-bit pages: • Program each Espia to write on aux buffer • Frame end (all adapters finished) copy from aux. into target buffer • Inform waiting threads • Adapters are not synchronous • Memory copy with IRQ disabled  Kernel thread 5.8 GB Very high RAM 32 bit boundary 4 GB PCI 3.2 GB High RAM 800 MB Low RAM 0 MB

  30. Common CCD acq. Library • Reuse of common code  generic procedures + interfaces • Software “features” fallback if hardware has limited capabilities • High level Python implementation • Common TACO CCD interface • Interfaces: implicit  explicit • Image processing and data reduction as plugins (C++) • Extensible interface through user-defined “features” (Maxipix) • Generic TANGO interface • Collaboration framework (ALBA)

  31. Current status x 20 x 10 + 1[+1] (C++) x 1 (Python) x 5 + 1

  32. Conclusions • Significant number of supported 2D detectors • This number keeps raising … • New detectors demand high performance control • Experience in high speed acquisitions • Stable low level driver (Sarnoff failed only once…) • Functional high level interface • Never-ending project … (sub-projects) • Common image acquisition library will help!
