A real time data exchange on demand system for transferring real time data between a host processor and a target processor is described. The target processor includes a real time target exchange library and API library interface to a target application. The host processor includes a target server, a real time data exchange API interface to a host data exchange application and a real time data exchange dynamic link library. An interconnection data link is coupled between said real time target exchange library on said target processor and said real time data exchange dynamic link library on said host processor. The host processor includes a user interface for programming real time data exchange transfer points for data exchange into the target processor that are passed down to the target processor via the interconnection data link. The target processor has programmable triggers that are programmed by the transfer points that call an appropriate real time data exchange routine to do the data transfer.

Real-time data exchange on demand

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.

Multiprocessor emulation support using dynamic linking

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.
