SAR ATR Hourfor the SLAAC Fall ‘99 Retreat Intro/Module Performance Goals: Brian Bray FOA: Scott Hemmert SLD: Steve Crago CDI: Mike Wirthlin Wrap-up (Good/Bad/Future): Brian Bray
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 (CC&D) 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) *Mpixel in downsampled space microprocessor = PowerPC 750 @ 400Mhz
The Good • ACS CDI Performance • JHDL • BYU students and faculty • Virtex parts • on-chip memory • large amounts of logic
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?
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
