Abstract
A configurable SIMD engine in a video processor for executing video processing operations. The engine includes a SIMD component having a plurality of inputs for receiving input data and a plurality of outputs for providing output data. A plurality of execution units are included in the SIMD component. Each of the execution units comprise a first and a second data path, and are configured for selectively implementing arithmetic operations on a set of low precision or high precision inputs. Each of the execution units have a first configuration and a second configuration, such that the first data path and the second data path are combined to produce a single high precision output in the first configuration, and such that the first data path and the second data path are partitioned to produce a respective first low precision output and second low precision output in the second configuration.
