Abstract: A system and method provide adaptive frequency scaling for predicting the load on a processing unit and dynamically changing its clock frequency while keeping the synchronization with other processing units. The amount of data in an input memory waiting to be processed is a good indicator of the current load and thus embodiments utilize the same concept for predicting the load on the processing unit. The frequency of operation is thus changed on the basis of the percentage of memory being occupied by its input data. Algorithms according to embodiments allow the processing unit to use the maximum possible clock frequency only when it is required and to run at some lower frequencies in low processing power requirements. Operating the circuit at low frequency helps in reducing power consumption.

Abstract: A pipeline accelerator includes a bus and a plurality of pipeline units, each unit coupled to the bus and including at least one respective hardwired-pipeline circuit. By including a plurality of pipeline units in the pipeline accelerator, one can increase the accelerator's data-processing performance as compared to a single-pipeline-unit accelerator. Furthermore, by designing the pipeline units so that they communicate via a common bus, one can alter the number of pipeline units, and thus alter the configuration and functionality of the accelerator, by merely coupling or uncoupling pipeline units to or from the bus. This eliminates the need to design or redesign the pipeline-unit interfaces each time one alters one of the pipeline units or alters the number of pipeline units within the accelerator.
