The latest incarnation of the company's inter-processor communications (IPC) software library, IPC 2.0, adds support for Serial RapidIO (SRIO), making the application a contender for DSP applications employing switched serial fabric-based VPX technology. Supporting two communications models, the software's messaging API provides a foundation for control and synchronization between processors with priority-based, flow-controlled, and acknowledged messages. It also provides a global shared memory model that is used for the transfer of large datasets. IPC 2.0 supports the company's latest VPX and VPX-REDI cards, including single- and dual-core versions of the CHAMP-AV6 DSP engine and the single- and dual-core versions of the VPX6-185 single-board computer. Providing prioritized, queue-driven flow-controlled message passing for command and control, as well as block transfers for high-volume time-perishable data, the software includes a POSIX-compliant interface with standard open, close, read, write, and ioctl functions. IPC 2.0 operates under the VxWorks 6.3 real-time operating system. For more details, contact Jerri-Lynne Charbonneau at CURTISS-WRIGHT CONTROLS EMBEDDED COMPUTING, Leesburg, VA. (613) 254-5112.
