Abstract: Methods and systems to interface a SIMD array to a host computer operating system using one or more context sensitive filter controllers. The filter controllers or drivers can intercept I/O requests from the host operating system and redirect the requests to the SIMD array. By using the filter controllers, the SIMD array can be viewed by the host operating system as a file, database engine, and/or other storage device including a hard drive. Based on the request from the host, including the data content, document type, document content, and document or data format associated with the request, the filter controllers can provide a set of instructions to process the request using the SIMD array, while exploiting the parallel processing power of the SIMD array.
