摘要： A system and method provides hardware support for fast software emulation of unimplemented instructions using issue trap logic that determines the instruction type and parameter fields of an unimplemented instruction when an exception is triggered and uses the fields to branch directly to emulation code specific to an unimplemented instruction having the determined instruction type and parameter fields.

摘要： In a microprocessor, apparatus and method coordinate the fetch and issue of instructions by rotating multiple, fetched instructions into an issue order prior to issuance and dispatching selected of the issue ordered instructions. The rotate and dispatch block including a mixer for mixing newly fetched instructions with previously fetched and unissued instructions in physical memory order, a mix and rotate device for rotating the mixed instructions into issue order, an instruction latch for holding the issue ordered instructions prior to dispatch, and an unrotate device for rotating non-issued instructions from issue order to physical memory order prior to mixing with newly fetched instructions. During the fetch cycle, multiple instructions are simultaneously fetched from storage in physical memory order and rotated into a PC-related issue order within the rotate and dispatch block. During the next clock cycle, selected ones of the previously fetched and rotated instructions enter the issue cycle, a new set of instructions are fetched in physical memory order, the previously fetched and rotated instructions which were not issued are rearranged into physical memory order and mixed in physical memory order with the newly fetched instructions, together all fetched and non-issued instructions are rotated into issue order prior to the next issue cycle, and so forth until all instructions have passed through the pipeline.

摘要： In one embodiment, a method is contemplated. Access to a hardware accelerator is requested by a user-privileged thread. Access to the hardware accelerator is granted to the user-privileged thread by a higher-privileged thread responsive to the requesting. One or more commands are communicated to the hardware accelerator by the user-privileged thread without intervention by higher-privileged threads and responsive to the grant of access. The one or more commands cause the hardware accelerator to perform one or more tasks. Computer readable media comprises instructions which, when executed, implement portions of the method are also contemplated in various embodiments, as is a hardware accelerator and a processor coupled to the hardware accelerator.

摘要： A system and method providing a programmable hardware device within a CPU. The programmable hardware device permits a plurality of instructions to be trapped before they are executed. The instructions that are to be trapped are programmable to provide flexibility during CPU debugging and to ensure that a variety of application programs can be properly executed by the CPU. The system must also provide a means for permitting a trapped instruction to be emulated and/or to be executed serially. Related Applications

摘要： A system and method for profiling runtime system events of a computer system may include associating a data source type with detected system events. The system events may be detected dependent on information included in a reply message received by a processor in response to a data request or other transaction request message. The reply message may include information characterizing a source type of a source of data included in the reply message. The source type information may indicate that the source is remote or local; that it is a shared or a private storage location; that the data is supplied via a cache-to-cache transfer; or that the data is sourced from a coherency domain other than that of the requesting process. Instructions, events, messages, and replies may be sampled, and extended address information corresponding to the samples may be stored in an event set database for performance analysis.
