Use Memory and I/O Device Data in Processor Simulation

The Processor I/O sub-library in SoC Blockset™ contains blocks that simulate the data transfer between the processor system and memory or I/O devices in the SoC application. Processor I/O blocks including the following:

Memory

• Register Write

• Register Write

• Stream Read

External

• TCP Read

• TCP Write

• UDP Read

• UDP Write

In simulation, an IO Data Source block sends data messages to the Processor I/O block. The IO Data Source block can generate data from one of three sources:

• Replay recorded data from file

• From input port

• Zeros

These modes allow tasks to simulate using either previously recorded or data generated in simulation.

For event-driven task, the IO Data Source sends a message to the connected Processor I/O block and event signal to the Task Manager block to start the task containing the Processor I/O block. This configuration allows simulation of asynchronous tasks with data recorded from actual
