Curtiss-Wright has debuted a new quad PowerPC-based 6U VME64x board that supports the StarFabric point-to-point, switched backplane and features quad 1 GHz PowerPC 7457 processors tightly-coupled in a shared memory architecture.
When used in conjunction with symmetric multi-processing (SMP) capable operating systems, such as Linux, the Manta QX3 enables software-transparent performance scaling while the operating system distributes tasks across multiple processors.
The Manta QX3 also provides a wide range of memory options including 512 MB,
1GB, or 2GB of DDR SDRAM with ECC protection. Each of the board’s 7457 CPUs is
supported by up to three levels of enhanced cache memory. Integrated into each
CPU’s core is 512 KB of L2 cache which operates at speeds matching the
processor’s frequency. Each 7457 CPU also provides up to 2 MB of backside L3
cache and can be optionally configured with 2 MB of private memory which
functions as a high-speed "scratch pad".
This air-cooled VME64x board is offered in a range of ruggedization levels,
spanning from commercial to extended temperature versions qualified for elevated
shock and vibration environments. A conduction-cooled version of the Manta QX3,
supporting card-edge temperatures of -40C to +85C, is also planned.
The Manta QX3 supports its quad 7457 processors with an on-board Discovery III
advanced system/memory controller. The Discovery III integrates fast memory,
dual PCI buses with PCI-X support, and abundant I/O functionality, all routed
through a high-bandwidth crossbar.
It also incorporates a 64-bit, 133MHz PMC site; two StarFabric interfaces; 5Gbps total full duplex; two Gigabit Ethernet (10/100/1000) ports; four RS-232 ports; two RS-422/485 ports and dual optional IEEE 1394a (FireWire) ports.
Software support includes board support packages for VxWorks, INTEGRITY and Symmetric Multiprocessing (SMP) Linux. The Manta QX3 ships with STAR/ASTRix boot, diagnostic, and system monitor firmware. The onboard firmware also features user customizable power-up and built in test capabilities.
For DSP applications, Curtiss-Wright offers its extensible DSP Math Library,
hand-coded and optimized for the PowerPC and Altivec technologies, as well as
Global Buffer Management software (GBM) to facilitate programming of fabric
based system applications.
