Dy 4 Unveils Rugged PMC Board with Dual PowerPC 7447 Processors

4/13/2004 - Dy 4 Systems (Dy 4), a wholly owned subsidiary of Curtiss-Wright Controls, Inc., announces the newest member of its CompactCore family of small form-factor embedded computing products, the PMC-106 symmetric multiprocessing dual PowerPC 7447 processor PMC board. The PMC-106 addresses the growing need for standards-based processing modules that fit into small spaces.

The PMC-106 comes equipped with one or two Altivec-enabled Motorola MPC7447 processors operating at up to 1 GHz, each with 64 Kbytes of L1 cache, and 512 Kbytes of internal L2 cache. The dual processor version can support operating systems, such as Linux that provide symmetric multiprocessing. The PMC-106 provides 256 Mbytes of double-data rate (DDR) SDRAM, providing 2 GB/sec of peak memory bandwidth. This memory incorporates error checking and correcting (ECC) circuitry for applications demanding extremely high reliability. A 64-bit, 133MHz PCI-X interface offers more than 1GB/sec (peak) transfer rate between the PMC and the host card.

The PMC-106 supports a Gigabit Ethernet interface enabling high-performance networking with the newest generation of systems. The interface is backwards compatible with both10Mbps and 100Mbps Ethernet networks, and automatically adapts to the required speed. The PMC-106 is also equipped with two EIA-232/422 serial interfaces that operate at up to 115 Kbps. Additionally the card provides six general purpose LVTTL discrete I/O signals that are interoperable with standard 5V TTL logic.

Robert Hoyecki, Dy 4 DSP product manager said, "Many of our customers' systems include some form of specialized I/O card that they design themselves. Rather than including processors in their design, customers are incorporating a processor PMC. By taking this approach, their design effort is simplified by focusing strictly on their I/O problem, and the resulting product is easily upgraded with faster processors as they become available from the COTS vendor community."

The PMC-106 offers the unique capability of allowing users to select the processor clock frequency, and thus the power dissipation, to match their specific application needs. The clock frequency is software programmable and therefore in-system upgradeable should new revisions of application software require higher processing performance. To cool the PMC-106, Dy 4 has developed an innovative cooling frame that minimizes component operating temperatures, while staying compliant with the VITA 20 standard for conduction cooled PMCs.

Operating system support is available or planned for Wind River VxWorks/Tornado, Green Hills INTEGRITY and Timesys Linux. The Dy 4 software suite also includes a run-time library supporting applications compiled to run without any RTOS. Dy 4's proven IXLibs-AV DSP function library is supported for use on the PMC-106.
