Embedded Pentium Processing CAB System Topologies The CAB system on the Mamba-100 is designed to operate in The Viper-Digital can transfer acquired images to the host PCI bus three different configurations. These topologies allow developers for host based processing, or across the Coreco Auxiliary Bus to adapt their image processing algorithms to leverage multiple (CAB) at 200 Mbytes/sec to the Mamba products. parallel processors or pipeline processing techniques to gain and Mamba-100 increase processing performance in several folds. Multicast Mode The Mamba-100 is a highly integrated, Pentium III based embedded vision processor designed to off-load time-critical and compute intensive tasks from the host. The advanced technology offered by Intel's Pentium III employs The CAB’s Multicast mode allows images to be sent for concur- enhanced MMX rent processing on two or more Mamba-100s. Multicast mode can instructions along with a newly introduced Streaming SIMD also be used to perform pipeline processing. Extensions (SSE), memory and cache management instructions to speed up data processing. A central feature of the Mamba-100 is Round-Robin Mode the Coreco Auxiliary Bus (CAB), a dedicated high-speed board-to- board communication bus (200 Mbytes/sec.) that facilitates fast data transfers. Coreco's Viper frame grabbers use the CAB to transfer image data to the Mamba-100. Other features include, a flexible software development environment and the ability to configure multi-board architectures. The CAB transfers image data from the Coreco Viper series of intelligent frame grabbers, which includes the Viper-RGB for color applications, the Viper-Digital for integrating cameras with multiple digital inputs, the Viper-CamLink a camera link-based frame grabber and the Viper-Quad for simultaneous acquisition from up to four cameras. The Viper-Quad The CAB’s Round-Robin mode allows successive images to be is ideally suited for semiconductor, reticule inspection, and sent to different Mamba-100s in the system for concurrent multi-stage inspection applications requiring acquisition of processing. For example, the Viper-Digital, while grabbing multiple views of an object. continuously, can transfer the first image to the first Mamba-100, the second image to the second Mamba-100, and so on, for processing.
