1. A device for processing a signal, comprising: a processing module, including a first processor and an internal memory, configured to process first domain data; a domain conversion hardware, separate from the processing module and including a second processor, configured to use the second processor to perform domain conversion without using the internal memory or the first processor of the processing module, the domain conversion hardware configured to convert second domain data into the first domain data; and shared memory separate from and in communication with the processing module and the domain conversion hardware, the shared memory configured to receive the second domain data prior to conversion into the first domain data by the domain conversion hardware, the shared memory further configured to receive the converted first domain data from the domain conversion hardware prior to processing performed using the first processor of the processing module, wherein the processing module is further configured to provide control data to the domain conversion hardware via the shared memory, the control data specifying parameters of transforms performed during operation of the domain conversion.
