I/O DLL Kit

The I/O DLL kit provides a means for extending the functions of the simulator debugger on High-performance Embedded Workshop. This kit supports the creation of I/O DLLs. The I/O DLL refers to a DLL(*1)  that operates in cooperation with the simulator engine of the simulator debugger.

Once the necessary settings are made, the simulator debugger allows you to load an I/O DLL and operate it synchronously with the timing at which instructions are single-stepped, memory is read or written or an interrupt occurs. That way, the operation of the input/output ports or the internal peripheral functions of the microcomputer can be simulated as a means of debugging the target program. Furthermore, linked operation with an external tool can be realized by, for example, sending and receiving data to and from that tool.

Any desired I/O DLL can be created by using C/C++ language. To create an I/O DLL, you need to have Microsoft Visual C++, a Windows application development environment available on the market.

*1. DLL is the acronym of Dynamic Link Library. This is a function of the operating system that allows you to save executable routines (routines that supply a specific function or a set of functions) to be saved separately as a file with the extension ".dll". These routines are loaded only when they are needed by the calling program.

Linkage between the simulator enigine and I/O DLL

The simulator engine calls the functions that have been predefined on the I/O DLL side synchronously with the timing shown below:

  • After executing one instruction (number of execution cycles)
  • Before execution (PC value)
  • When the target is reset
  • When an interrupt occurs
  • Immediately before memory read (address information)
  • Immediately after memory write (address information)

Conversely, the following functions that have been made public for the simulator engine can be called from the I/O DLL side:

  • Get memory contents
  • Set a memory value
  • Get a register value
  • Set a register value
  • Interrupt occurrence
  • Confirm interrupt occurrence condition
  • Inspect the total number of cycles executed

Supported Simulator Debuggers

This I/O DLL kit is available for the following simulator debuggers in the compiler packages :

Note: This I/O DLL kit is NOT supported by the M3T-PDxxSIM simulator debuggers. For M3T-PDxxSIM, use the PDxxSIM I/O DLL Kit.

 

Development Tools Used

To create an I/O DLL, you need to have Microsoft Visual C++, a Windows application development environment available on the market.
