摘要： An apparatus, system, and method are disclosed for testing data compression and data encryption circuitry. A pattern configuration module generates initial pattern parameters. Holding registers store the initial pattern parameters. A pattern generation module generates patterns for compression/encryption logic. A detection module detects a failure of the compression/encryption logic. The failure of the compression/encryption logic may be a cyclic redundancy check failure of a decompression module and/or a message authentication code failure of a decryption module.

摘要： A method for equalizing the bandwidth of requesters using a shared memory system is disclosed. In one embodiment, such a method includes receiving multiple access requests to access a shared memory system. Each access request originates from a different requester coupled to the shared memory system. The method then determines which of the access requests has been waiting the longest to access the shared memory system. The access requests are then ordered so that the access request that has been waiting the longest is transmitted to the shared memory system after the other access requests. The requester associated with the longest-waiting access request may then transmit additional access requests to the shared memory system immediately after the longest-waiting access request has been transmitted. A corresponding apparatus and computer program product are also disclosed.
