A simulation method using predefined data flows and microprocessor task is disclosed for simulating the performance of a plurality of microprocessors interacting with shared resources, such as a memory. In an example of image processing, the three major functions of I/O control, character isolation, and character recognition are each implemented with a separate microprocessor, whereas data is all stored in a single memory. Data flows to and from each microprocessor through buffers which may be serial, parallel, or include hardware functions. The data rate, buffer size and data source or destination are specified for each data flow. the time required for each microprocessor task is manually estimated in advance based upon the complexity of the task.
