    摘要: An apparatus is disclosed for operating a symmetric cipher engine (SCE) in cipher-block chaining (CBC) mode, the apparatus comprises a crypto operation hardware comprising said SCE, an XOR stage, an apparatus for storing a chaining value comprising a state register of said SCE, an input latch supplying said crypto operation hardware with data, and an output latch. The data may be reordered for decipher operations. Furthermore, a method is disclosed for operating a SCE in CBC mode, wherein the method involves a crypto operation hardware that comprises said SCE and an XOR stage supplied with data. The method may also comprise using a state register of said SCE to apply a chaining value. Said method may comprise reordering data supplied to said crypto operation hardware for decipher operations.

    摘要: A command is issued to reset one or more pending interrupt indicators and arbitrate for ownership of the interrupt. Responsive to a processor receiving the command, a check is made of a selected pending interrupt indicator. If the selected pending interrupt indicator is not set, another pending interrupt indicator is checked, instead of providing a negative response and reissuing the command. In this way, one dequeue command can replace multiple dequeue commands and the overhead of leaving and re-entering the interrupt handler is reduced. A negative response is reserved for those situations in which there are no pending interrupt indicators to be reset.

    摘要: A system, method and computer program product for translations in a computer system. The system includes a general purpose register containing a base address of an address translation table. The system also includes a millicode accessible special displacement register configured to receive a plurality of elements to be translated. The system further includes a multiplexer for selecting a particular one of the plurality of elements from the millicode accessible special displacement register and for generating a displacement or offset value. The system further includes an address generator for creating a combined address containing the base address from the general purpose register and the generated displacement or offset value.
