The System Level Applications of Adaptive Computing (SLAAC) project is defining an
open, distributed, scalable, adaptive computing systems architecture based on a highspeed
network cluster of heterogeneous, FPGA-accelerated nodes. Two reference implementations
of this architecture are being created. The Research Reference Platform
(RRP) is a MyrinetTM cluster of PCs with PCI-based FPGA accelerators (SLAAC-1).
The Deployable Reference Platform (DRP) is a Myrinet cluster of PowerPCTM nodes
with VME-based FPGA accelerators (SLAAC-2) and a commercial 6U-VME quad-
PowerPC board (CSPI M2641S) serving as the carrier. A key strategy proposed for
successful ACS technology insertions is source-code compatibility between the RRP and
DRP platforms. This paper focuses on the development of the SLAAC-1 and SLAAC-2
accelerators and how the network-centric SLAAC system-level architecture has shaped
their designs. A preliminary mapping of a Synthetic Aperture Radar/Automatic Target
Recognition (SAR/ATR) algorithm to SLAAC-2 is also discussed.
