General Micro Systems, Inc.0 MHz Atlas-C is the computer industry's first multiprocessor CompactPCI board based on the new Intel Coppermine-256 Flip Chip Processors. Atlas-C provides built-in support for symmetric and real-time asymmetric multiprocessing, which enables its two Coppermine-256 processors to work together in parallel on the same program, transparent to the programmer and the application.

Atlas-C features a pair of low-power (15W), 550-MHz Coppermine processors, with 850-MHz clock speeds expected by Q1 2000. Each processor is equipped with 256 kbytes of no-wait-state on-die Cache. The two processors also share up to 1 Gbyte of 100-MHz synchronous DRAM main memory. The processors, cache and memory are linked via a 100-MHz local bus, which is an extension of Intel's Front Side Bus (FSB).

Atlas-C provides the most versatile I/O and networking options of any Pentium based multiprocessor CPU board. Included are dual 10/100-Mbit/sec Ethernet interfaces (twisted pair), a 40-Mbyte/sec UltraWide SCSI interface, and a 64-bit AGP graphics engine with four Mbytes of video RAM optimized for 3D rendering. Also available are two Ultra-DMA 33 IDE interfaces, a pair of USB ports, dual serial I/O with optional RS422 drivers and a parallel port.

Asymmetrical multiprocessing is an innovative form of de-coupled multiprocessing based on GMS' new RAMP (Real-time Asymmetric Multi Processing) technology. The RAMP microkernel works hand in hand with RTOSs like VxWorks, enabling a single master processor to coordinate the activities of multiple slave processors, each executing its tasks fairly independently out of shared memory.

For applications requiring high performance at a reduced cost, Atlas-C is also available with a single 466-MHz Celeron PPG370 processor, scaleable to 500 MHz.

Atlas-C I/O is available via an 80 mm rear panel I/O, which can also accommodate a 2.5in. 9GB IDE drive. For applications that must be deployed without a rotating hard disk, the board also provides up to 340 Mbytes SanDisk 1.5in. Flash IDE on the rear panel.

Pricing for Atlas-C is approximately $2299 less processor and memory (pricing at time of publication).
