摘要： Software can freeze portions of a pipeline operation in a processor by asserting a predetermined freeze register in the processor. The processor halts operations relating to portions of a common pipeline processing in response to an asserted freeze register. Processor resources that operate downstream from the common pipeline continue to process any scheduled instructions. The processor is prevented from initiating any context switching in which a processor resource is allocated to a different channel. The processor stops supplying any additional data to downstream resources and ensures that the interface to downstream resources is clear of previously sent data. The processor prevents state machines from making additional requests. The processor asserts an acknowledgement indication in response to the freeze assertion when the processing has reached a stable state. Software is allowed to manipulate states and registers within the processor. Clearing the freeze register allows processing to resume.

摘要： A processor having multiple independent engines can concurrently support a number of independent processes or operation contexts. The processor can independently schedule instructions for execution by the engines. The processor can independently switch the operation context that an engine supports. The processor can maintain the integrity of the operations performed and data processed by each engine during a context switch by controlling the manner in which the engine transitions from one operation context to the next. The processor can wait for the engine to complete processing of pipelined instructions of a first context before switching to another context, or the processor can halt the operation of the engine in the midst of one or more instructions to allow the engine to execute instructions corresponding to another context. The processor can affirmatively verify completion of tasks for a specific operation context.

摘要： An apparatus and method for servicing multiple graphics processing channels are described. In one embodiment, a graphics processing apparatus includes a scheduler configured to direct servicing of a graphics processing channel by issuing an index related to the graphics processing channel. The graphics processing apparatus also includes a processing core connected to the scheduler. The processing core is configured to service the graphics processing channel by: (i) correlating the index with a memory location at which an instance block for the graphics processing channel is stored; and (ii) accessing the instance block stored at the memory location.

In one aspect, a system comprises a first circuit in a first dynamic clock domain of a plurality of dynamic clock domains, a processor configured to execute software instructions to generate a request for a status of the first circuit, and a second circuit coupled to the first circuit and to the processor. The second circuit, outside the first dynamic clock domain, is configured to shadow a status of the first circuit and to respond to the request for the status of the first circuit with the shadowed status.

摘要： A system and method schedules command streams for processing by a variety of consumers. A single command stream is parsed and commands included in the command stream are output to one of the variety of consumers at a time. A pre-emptive scheduling mechanism is used so that a first consumer may yield to a second consumer when the first consumer has received a sufficient amount of commands. The pre-emptive scheduling enables several of the consumers to process commands concurrently. The pre-emptive scheduling mechanism may be implemented by a device driver inserting yield commands into the command stream or by a unit parsing the command stream.

摘要： A data processing system can establish or maintain data coherency by issuing a data flush operation. An agent can initialize a first flush operation by writing to a flush register. The agent can determine that the flush operation is complete by reading a status indicator from a status register. Additional agents can independently issue flush operations during the pendency of the first flush operation. A second flush instruction and any additional flush instructions that issue during the pendency of the first flush operation set a flush pending indicator in a status register. Once the first flush operation completes, the host performs all pending flush operations in a single second flush operation. The status indicator does not indicate a completed flush operation for the first flush operation until all flush operations are complete. Multiple co-pending flush operations are collapsed into at most two flush operations.
