JULY 14--Traquair Data Systems Inc. (Ithaca, NY; www.traquair.com) is supporting video frame capture via FireWire for the microline family of embedded DSP boards, which targets embedded DSP OEMs. Existing microline support for 400-Mbit/s IEEE 1394a FireWire communications has been enhanced by the addition of software support for FireWire cameras, allowing microline developers access to an image frame capture and processing platform for a range of embedded real-time imaging applications. Moreover, single or multiple camera configurations can be supported.
An Instrumentation & Industrial Digital Camera (IIDC) FireWire Camera compliant software function library allows developers to control camera operation from DSP resident application code. Various video modes and formats are supported, ranging from 8- to 24-bits/pixels and 160 x 120 to 1600 x 1200 frame sizes. Additional software-configurable features are available based on individual camera functionality. Examples include adjustable frame rates, brightness, autoexposure, sharpness, white balance, hue, saturation, gamma, shutter, gain, trigger mode, zoom, pan, tilt, and optical filter.
Developers can process the captured image data in real time with user-programmable DSP and FPGA resources provided on microline DSP boards. The flagship of the microline family, the C6713Compact provides a high-performance TMS320C6713 DSP processor (maximum performance 1800 MIPS or 1350MFLOPS), a Virtex-II FPGA in a 256kGate, 512kGate, or 1MGate density configuration, and an on-board two-port IEEE 1394a FireWire interface. The 512kGate and 1MGate can master the 64 Mbytes of on-board memory, enabling configurations for high-speed 2-D convolution.
