摘要： Systems and methods are disclosed for performing multiple processing of data in a network. In one embodiment, the network comprises a first display pipeline that is formed in real time from a plurality of possible display pipelines and that performs at least a first processing step on received data. A buffer stores the processed data and a second display pipeline that is formed in real time from a plurality of possible display pipelines performs at least a second processing step on stored data.

摘要： Methods and apparatus are provided for generating interrupts associated with the completion of data processing. An external host may pass a first data block to a first processing engine and later pass a second data block to a second processing engine. In typical implementations, the external host expects that processing of the first data block completes first. To prevent errors and faults on the part of the external host, an interrupt associated with the processing of the second data block completing first is collapsed onto the first data block.

摘要： Methods and apparatus are provided for efficiently normalizing and denormalizing data for cryptography processing. The normalization and denormalization techniques can be applied in the context of a cryptography accelerator coupled with a processor. Hardware normalization techniques are applied to data prior to cryptography processing. Context circuitry tracks the shift amount used for normalization. After cryptography processing, the processed data is denormalized using the shift amount tracked by the context circuitry.
