摘要： In a processor having an address translation table, a method includes providing a logical address and control signal. When the control signal has a first value, a first physical address is provided corresponding to the logical address, and when the control signal has a second value, a second physical address is provided. The first physical address and the second physical address are stored in at least one valid entry of the address translation table. In one case, the first physical address is stored in a first valid entry having a tag field which matches the logical address and the second physical address is stored in a second valid entry having a tag field which matches the logical address. Alternatively, the first physical address is stored in a first field of a first valid entry and the second physical address is stored in a second field of the first valid entry.

摘要： A method includes providing an effective address, providing an address space identifier which identifies a currently executing process, providing a mapping modifier to form a modified address space identifier where the mapping modifier is based on at least one external signal generated outside the processor, using the effective address and the modified address space identifier to form a logical address, and providing a physical address corresponding to the logical address. When the effective address has a first effective address value, the address space identifier has a first address space identifier value, and the mapping modifier has a first mapping value, the physical address has a first physical address value. When the effective address has the first effective address value, the address space identifier has the first address space identifier value, and the mapping modifier has a second mapping value, the physical address has a second physical address value.

摘要： A method includes providing an integrated circuit having a plurality of debug resources. The debug resources are usable exclusively for debug operations. The debug operations include operations directed by debug software executed by the integrated circuit and operations directed by external debug hardware which is external to the integrated circuit. The method further includes enabling availability of a first portion of the debug resources for use by the debug software, where a second portion of the debug resources are committed for exclusive use by the external debug hardware. The first portion is exclusive of the second portion. The method includes performing operations directed by the debug software using at least one debug resource of the first portion of the debug resources and operations directed by the external debug hardware using at least one debug resource of the second portion of the debug resources.

摘要： Task context information is transferred concurrently from a processor core to an accelerator and to a context memory. The accelerator performs an operation based on the task context information and the context memory saves the task context information. The order of transfer between the processor core is based upon a programmable indicator. During a context restore operation information is concurrently provided to data bus from both the accelerator and the processor core.

摘要： A data processing system includes a processor core and ordering scope manager circuitry. The processor core sends an indication of a first ordering scope identifier for a current ordering scope a task currently being executed by the processor core and a second ordering scope identifier for a next-in-order ordering scope of the task. The ordering scope manager receives the indication the first and second ordering scope identifiers from processor core, and, provides a no task switch indicator to the processor core in response to determining that the first task is a first-in-transition-order task for the first ordering scope identifier and that processor core is authorized to execute the next-in-order ordering scope. The processor core transitions from executing in the current ordering scope to executing in the next-in-order ordering scope without performing task switch in response to the no task switch indicator being provided.

摘要： Each task assigned to a core can be considered an “active” task. Sequential strobe signals of a watchdog signal can be spaced apart in time by a certain duration. The duration between strobe signals is longer than the expected duration of an active task. By knowing that all tasks being monitored are expected to execute within an expected amount of time, the duration between the strobe signals can be set to be longer than that expected amount of time. If a task has not transitioned to inactive by a next strobe, a watchdog error has occurred.

摘要： A floating point value can represent a number or something that is not a number (NaN). A floating point value that is a NaN having data field that stores information, such as a propagation count that indicates the number of times a NaN value has been propagated through instructions. A NaN evaluation instruction can determine whether one or more operands is a NaN operand of a particular type, and if so can generate a result that is a NaN of a different type. An exception can be generated based upon the NaN of the different type being provided as a resultant.

摘要： A data processing system includes a processor core and a hardware module. The processor core performs tasks on data packets. The hardware module stores a first ordering scope identifier at a first storage location of the ordering scope manager. The first ordering scope identifier indicates a first ordering scope that a first task is operating in. The ordering scope manager increments the first ordering scope identifier to create a new ordering scope identifier. In response to determining that the processor core is authorized to transition the first task from the first ordering scope to a second ordering scope associated with the new ordering scope identifier, the ordering scope manager provides hint information to the processor core. The processor core transitions from the first ordering scope to the second ordering scope without completing a task switch in response to the hint information.
