Operating Systems for DSP Applications
Curtiss-Wright Controls Embedded Computing offers customers with several choices of real-time operating systems for use on its CHAMP product line. The choices have commonality with those available for use on PowerPC based SBCs, so developers can have a single tool-chain to use on systems involving both DSPs and SBCs. Currently available operating system choices for use with the CHAMP product line include: INTEGRITY by Green Hills; VxWorks by Wind River; Linux from Curtiss-Wright; Gedae by Gedae Inc..
Digital Signal Processing Libraries
The CHAMP DSP products derive their floating-point performance from the PowerPC AltiVec unit. Programming the AltiVec is complex. For customers who prefer to focus on their algorithms, Curtiss-Wright offers the Continuum Vector DSP function library. Continuum Vector provides Application Programming Interfaces (APIs) which are compatible with other popular board vendor function library APIs and also with the open-standard Vector Signal Image Processing Library (VSIPL Core Lite profile). This greatly simplifies the effort associated with porting existing software from other platforms to Curtiss-Wright hardware. Many functions are available in both single and double precision arithmetic.
Inter-Processor Communications
Military DSP applications employ multiple processors operating in a pipeline or in parallel. In either case, data must be transferred quickly and efficiently between the processors. Curtiss-Wright offers the Inter-Processor Communications (IPC) library to provide messaging and bulk data transfers in a multi-processor system. IPC provides a hardware-neutral interface for task-to-task communications. IPC will run with the same API on a single processor, or on a large system based on the both the Serial RapidIO and StarFabric switched interconnects.
