A method for tracing a multi-tasking embedded pipelined processor includes executing compiled code including trace controls. Tracing is initiated when the execution of the compiled code is initiated. Tracing is stopped when execution of the compiled code is completed. A trace record is formed during tracing. The trace record includes a processor mode indication, application space identity value and an instruction architecture set mode indication.

A system and method for program counter and data tracing is disclosed. Generated trace messages are included within a trace word format and stored in trace memory, thereby enabling a reduction in the amount of trace storage required.

A configurable coprocessor interface between a central processing unit (CPU) and a coprocessor is provided. The coprocessor interface has an instruction transfer signal group for transferring different instruction types from the CPU to the coprocessor, sequentially or in parallel, a busy signal group, for allowing the coprocessor to signal the CPU that it cannot receive a transfer of one or more of the different instruction types, and an instruction order signal group for indicating to the coprocessor a relative execution order for multiple instructions that are transferred in parallel. In addition, the coprocessor interface includes separate data transfer signal groups for data being transferred from the CPU to the coprocessor, and for data being transferred from the coprocessor to the CPU, along with a data order signal group for indicating a relative order of data (if transferred out-of-order). The interface further includes signal designations which allow for multiple issue groups between the CPU and one or more coprocessors.

A system accessible by a test access port controller via a test access port interface includes a data register. The data register is selectable based on an instruction register signal in the test access port interface. The instruction register signal is derived form an instruction register in the test access port controller. A shift register is connected to a data input and a data output in the test access port interface and to the data register. The operation of the shift register is controlled based on an indication of a state of a test access port controller state machine that is received over the test access port interface.

An interface for transferring data between a central processing unit (CPU) and a plurality of coprocessors is provided. The interface includes an instruction bus and a data bus. The instruction bus is configured to transfer instructions to the plurality of coprocessors in an instruction transfer order, where particular instructions designate and direct one of the plurality of coprocessors to transfer the data to/from the CPU. The data bus is configured to subsequently transfer the data. Data order signals within the data bus prescribe a data transfer order that differs from the instruction transfer order by prescribing a transfer corresponding to a specific outstanding particular instruction, where the data transfer order is relative to outstanding instructions. The outstanding instructions are those of the particular instructions transferred to the one of the plurality of coprocessors that have not completed a data transfer.

A system and method for program counter and data tracing in a multi-issue processor is disclosed. Instructions are traced in program sequence order. In one embodiment instructions are traced in graduation order from a reorder buffer. The tracing mechanism of the present invention enables increased visibility into the hardware and software state of the processor core.

A system and method for providing efficient block transfer operations through a test access port uses a Fastdata register. The Fastdata register, in part, emulates a pending process access bit (“PrAcc”) typically found in a Control register associated with the test access port. When a Fastdata access (either a Fastdata upload or a Fastdata download) is requested by a probe coupled to the test access port, the Fastdata register is serially coupled to a data register also associated with the test access port. With these registers so coupled and through the operation of the Fastdata register, downloading and uploading data can be accomplished using a single register operation.
