    摘要： Call stack protection, including executing at least one application program on the one or more computer processors, including initializing threads of execution, each thread having a call stack, each call stack characterized by a separate guard area defining a maximum extent of the call stack, dispatching one of the threads of the process, including loading a guard area specification for the dispatched thread's call stack guard area from thread context storage into address comparison registers of a processor; determining by use of address comparison logic in dependence upon a guard area specification for the dispatched thread whether each access of memory by the dispatched thread is a precluded access of memory in the dispatched thread's call stack's guard area; and effecting by the address comparison logic an address comparison interrupt for each access of memory that is a precluded access of memory in the dispatched thread's guard area.

    摘要： An apparatus and method for evaluating a state of an electronic or integrated circuit (IC), each IC including one or more processor elements for controlling operations of IC sub-units, and each the IC supporting multiple frequency clock domains. The method comprises: generating a synchronized set of enable signals in correspondence with one or more IC sub-units for starting operation of one or more IC sub-units according to a determined timing configuration; counting, in response to one signal of the synchronized set of enable signals, a number of main processor IC clock cycles; and, upon attaining a desired clock cycle number, generating a stop signal for each unique frequency clock domain to synchronously stop a functional clock for each respective frequency clock domain; and, upon synchronously stopping all on-chip functional clocks on all frequency clock domains in a deterministic fashion, scanning out data values at a desired IC chip state. The apparatus and methodology enables construction of a cycle-by-cycle view of any part of the state of a running IC chip, using a combination of on-chip circuitry and software.

    摘要： In an embodiment, if a self thread has more than one conflict, a transaction of the self thread is aborted and restarted. If the self thread has only one conflict and an enemy thread of the self thread has more than one conflict, the transaction of the self thread is committed. If the self thread only conflicts with the enemy thread and the enemy thread only conflicts with the self thread and the self thread has a key that has a higher priority than a key of the enemy thread, the transaction of the self thread is committed. If the self thread only conflicts with the enemy thread, the enemy thread only conflicts with the self thread, and the self thread has a key that has a lower priority than the key of the enemy thread, the transaction of the self thread is aborted.
