摘要： A data processing system having a processor and a target device processes decorated instructions (i.e. an instruction having a decoration value). A device of the data processing system such as the processor sends transactions to the target device over a system interconnect. A decorated storage notify (DSN) transaction includes an indication of an instruction operation, an address associated with the instruction operation, and a decoration value (i.e. a command to the target device to perform a function in addition to a store or a load). The transaction on the system interconnect includes an address phase and no data phase, thereby improving system bandwidth. In one form the target device (e.g. a memory with functionality in addition to storage functionality) performs a read-modify-write operation using information at a storage location of the target device.

摘要： A data processing system has an interrupt controller which provides an interrupt request along with a corresponding interrupt identifier and a corresponding interrupt vector to a processor. If the processor accepts the interrupt, the processor returns the same interrupt identifier value by way of interrupt identifier, along with interrupt acknowledge, to the interrupt controller. An interrupt taken/not taken indicator may also be provided. The communications interface used to coordinate interrupt processing between the interrupt controller and the processor may be asynchronous.

摘要： A data processing device and methods thereof are disclosed. The data processing device can operate in three different modes. In a first, N-bit mode, the data processing device performs memory accesses based on N-bit values and performs arithmetic operations using N-bit values. In a second, hybrid N-bit/M-bit mode, the data processing device performs memory accesses based on M-bit values, where M is less than N, and performs arithmetic operations using N-bit values. In a third, M-bit mode, the data processing device performs memory accesses based on M-bit values and performs arithmetic operations using M-bit values. The three modes provide for compatibility with a wide range of applications. Further operation in the M-bit mode can provide a power savings when implementing applications compatible with that mode.

摘要： A first thread enters a polling loop to wait for a signal from a second thread before processing instructions dependent on the polling loop. When entering the polling loop, the first thread sets a reservation for a predetermined memory address. The first thread then executes a reservation-based instruction that can change the execution state of the first thread. Reservation circuitry of the processing device that was executing the first thread monitors the reservation. In the event that the reservation cleared, such as by the second thread modifying data at the predetermined memory address, the first thread is reinstated to its prior execution state. By using a hardware reservation mechanism to monitor for clearing of a set reservation, repeated memory accesses to the memory address by the first thread can be minimized or avoided while in the polling loop and other threads can be allowed to execute at the processing device with reduced interference from the waiting thread.

摘要： A processing system includes a plurality of coherency domains and a plurality of coherency agents. Each coherency agent is associated with at least one of the plurality of coherency domains. At a select coherency agent of the plurality of coherency agents, an address translation for a coherency message is performed using a first memory address to generate a second memory address. A select coherency domain of the plurality of coherency domains associated with the coherency message is determined at the select coherency agent based on the address translation. The coherency message and a coherency domain identifier of the select coherency domain are provided by the select coherency agent to a coherency interconnect for distribution to at least one of the plurality of coherency agents based on the coherency domain identifier.

摘要： A technique for scheduling execution of threads at a processor is disclosed. The technique includes executing a thread de-emphasis instruction of a thread that de-emphasizes the thread until the number of pending memory transactions, such as cache misses, associated with the thread are at or below a threshold. While the thread is de-emphasized, other threads at the processor that have a higher priority can be executed or assigned system resources. Accordingly, the likelihood of a stall in the processor is reduced.

摘要： A data processing system having a processor and a target device processes decorated instructions (i.e. an instruction having a decoration value). A device of the data processing system such as the processor sends transactions to the target device over a system interconnect. The transactions include an indication of an instruction operation, an address associated with the instruction operation, a decoration value (i.e. a command to the target device to perform a function in addition to a primary function of the executed instruction), and access permissions associated with the address. The target device (e.g. a memory with functionality in addition to storage functionality) determines whether a decoration operation specified by the decoration value is permissible based on the received access permissions. The target device performs the decoration operation if appropriate permissions exist.
