This paper presents the SONIC reconfigurable computing architecture and the first implementation, SONIC-1. SONIC is designed to support the software plug-in methodology to accelerate video image processing applications. SONIC differs from other architectures through the use of plug-in Processing Elements (PIPEs) and the Application Programmer’s Interface (API). Each PIPE contains a reconfigurable processor, a scaleable router that also formats video data, and a frame-buffer memory. The SONIC architecture integrates multiple PIPEs together using a specialised bus structure that enables flexible and optimal pipelined processing. SONIC-1 communicates with the host PC through the PCI bus and has 8 PIPEs. We have developed an easy to use API that allows SONIC-1 to be used by multiple applications simultaneously. Preliminary results show that a 19 tap separable 2-D FIR filter implemented on a single PIPE achieves processing rates of more than 15 frames per second operating on 512 x 512 video transferred over the PCI bus. We estimate that using all 8 PIPEs, we could obtain real-time processing rates for complex operations such as image warping.
