Current Challenge Problem Modules

• FOA (Focus of Attention)
• adaptive rank order quantization and multi-level
  morphology
• quad uP 2 Mpixels/sec ACS goal 10
  Mpixels/sec
• SLD (Second Level Detection)
• for in-the-clear scenarios
• adaptive attenuation estimation with binary
  template matching
• quad uP 16000 templates/sec ACS goal 80000
  templates/sec
• CDI (Contamination Distribution Indexer)
• for camouflage, concealment and deception (CCD)
  scenarios
• epsilon-contaminated mixtures model (10X more
  compute intensive than SLD)
• initial ACS goal is just the 2X not the 1X
  templates (90 of compute)
• quad uP 1600 templates/sec Inital ACS
  goal 16000 templates/sec
  End ACS goal (2X and 1X templates at 80000
  templates/sec)

The Good

• ACS CDI Performance
• JHDL
• BYU students and faculty
• Virtex parts
• on-chip memory
• large amounts of logic

4
The Bad

• We are behind
• Need an embedded Virtex based ACS board
• ACS parts with large penalty for large precision
  and FP operations
• What is the third generation ACS part?

5
The Future (As I See It)

• Bigger second generation ACS parts and better
  tools will come
• third generation will not be here in near term
• what will it be???
• Virtex-like with RISC core, I, D and DRAM
  interface?
• Will it be an improvement to compute tasks or
  just system on a chip applications
• PCI accelerator cards with multiprocessor
  workstation based groundstations
• will reduce the need for embedded VME hardware
• Annapolis Microsystems PCI
• WildSTAR is a significant improvement over
  WildForce
• SLAAC PCI?
• When compared to the WildSTAR, what design
  features can a SLAAC PCI Virtex board provide to
  overcome not being COTS and available now?
• Daughtercards for embedded VME multicomputers
• CSPI, Mercury
• many Mercury only shops for embedded VME
  multicomputers

6
Mercury Compatible ACS Node
Can SLAAC get access to these chips and enough
info to write SW drivers?
Mercurys PPC Daughtercard
ACS Daughtercard
Can this bus be run at a lower clock rate than
83.3Mhz?
CLK Gen
Boot EEPROM
How do others go about designing Mercury
compatible daughtercards?
