Abstract: A method and system for dynamically linked emulation with a mix of target debuggers on a host computer wherein a debugger for each processor on the target system connects to a target interface for that kind of processor. That target interface then communicates with an emulator dynamic loader on the host computer connected to an emulator. The target interface communicates with the dynamic loader on the host computer to determine if there is support for the desired kind on the emulator. If not a target interface is loaded to the emulator and connected to the already running software on the host. A connection to this target interface software on the emulator is then provided to the host computer.

Abstract: A data exchange system that exchanges data between processors is provided. The system includes a host processor and a target processor. Data is exchanged by forming a data pipeline between the target processor and the host processor. The data pipeline includes a data unit on the target processor, an emulator and a device driver on the host processor. The data exchange system sends data through the data pipe line by transferring the data from a target memory on the target processor with the data unit to the emulator. The data exchange system transfers the data from the emulator to the first device driver.

Abstract: In a pipeline data processor (11), an address pipeline (39, 41) id provided to hold the addresses of the instructions presently in the instruction pipeline (23, 25). The address pipeline facilitates tracing only executed instructions, and permits stopping the data processor during a branch delay slot without losing the branch information.
