Abstract: An embodiment includes at least one processing unit to perform at least first and second sets of diffusion-related operations to produce a resulting block from a data block, and that includes at least one stage and at least one other stage. The at least one stage is to select one of first operands and second operands input to the at least one other stage. The first and second operands are respectively associated with the first and second sets of operations, respectively. The at least one other stage involves arithmetic and logical operations common to both the first and second sets of operations. At least one other processing unit is to perform at least one set of cryptographic-related operations (different, at least in part, from the first and second sets of operations) on at least one of (1) another block to produce the data block and (2) the resulting block.

Abstract: A method and software architecture for grouping breakpoints. A plurality of breakpoints for halting execution of a program are created. A breakpoint group for logically associating one or more of the breakpoints is created. A portion of the breakpoints is added to the breakpoint group. The portion of the breakpoints is collectively enabled prior to executing the program by asserting an enable group command associated with the breakpoint group.

Abstract: A network forwarding device includes at least one physical interface, a framer and a network processor having multiple processing engines arranged as: a preparation stage provided on a first microengine of a processor having plural microengines the preparation stage to prepare the packet for processing, a processing stage provided on a second microengine of the processor, the processing stage to perform at least one crypto operation on the packet and a final stage provided on a third microengine of the processor to perform validate the packet in accordance with security associations and a switch fabric.
