1. 1. Introduction

■ About this manual

This document describes how to operate the SCSP / DSP / linker.

■ Summary

Create one "execution type DSP microprogram" by linking the "modules" prepared for each single function. There are two main types of modules: "EFFECT module" and "I / O module".
Module link order and input / output connections can be specified graphically on the screen.

The following hardware is the minimum required.

• A complete set of personal computer systems for Macintosh or Windows machines (a separate SCSI I / F board is required for Windows machines)

• SCSP software development board

• SCSI cable for connecting the above two points

■ Installation

Copy from the master disk to a suitable location on the hard disk.

■ Quick Start

This section provides an overview of the operations from startup to termination of the SCSP / DSP / linker.

● Step 1: Launch the linker application

Double-click the Linker icon in the finder to launch the application.

● Step 2: Open a new algorithm

Select “New” from the File menu, enter the file name and press the return key to open the new algorithm edit window. The file name is automatically given the extension ".YLI".

● Step 3: Check the SCSI ID

The SCSP / DSP / linker automatically sets the SCSI ID for communication with the development board at boot time. Select "SCSI ID" from the Option menu and check that the SCSI ID setting of the hardware switch on the development board matches the displayed ID.

warning	At this time, you can also change the SCSI ID by setting the ID and clicking “OK”. However, please note that if you set the SCSI ID incorrectly, the contents of the storage device (hard disk, etc.) connected by SCSI may be destroyed.

● Step 4: Build an effect algorithm

Step 4-1: Deploy the DSP I / O module
Select “I / O Modules” from the Window menu to open the “I / O Modules” window.
Double-click the "Input (input to DSP)" module, "Output (output from DSP)" module in the "I / O Module" window, or click to select and then click the "Select" button. .. The module will be placed in the last clicked position on the Algorithm Edit window.

reference

Dragging the "I / O Module" window to move it to a position where it does not overlap with the algorithm edit window so that the "I / O Module" window is always visible is convenient when arranging modules continuously.

Step 4-2: Place the effect module

Select “Effect Modules” from the Window menu to open the “Effect Modules” window.
Place the effect module in the same way as the DSP input / output module.

Step 4-3: Make connections between modules

Connect the modules placed in the algorithm edit window.
Click the output port of the module for which you want to extract the output sound data, and then click the input port of the module for which you want to input the sound data, and the modules will be connected. This connection determines the flow of sound data between each module.

● Step 5: Link

By selecting “Link” from the Process menu, the created effect algorithm will be linked. If the link is successful, the "Link Result Information" dialog is displayed. This dialog displays information about the usage of DSP-related hardware resources.

● Step 6: Download

By selecting “DownLoad” from the Process menu, the linked effect algorithm will be downloaded to the target (development board) hardware. At this stage, it will operate according to the effect algorithm created by the DSP.

● Step 7: Edit the effect parameters

The parameter edit window can be opened by double-clicking the margin (the part where characters are not displayed) in each module placed in the algorithm edit window, or by selecting and then selecting "Prameters" from the Window menu. It will be opened.
If you operate the scroll bar in this window with the mouse or enter a numerical value directly in the text box and confirm it with the return key, the parameter change result will be reflected in the effect in real time.

If you make an edit that changes the path of the sound data, the real-time edit of the parameter will not work from that point (in this state, “DownLoad” in the Process menu will be grayed out). In this case, link and download again to enable real-time editing of the parameters again.

● Step 8: Save as a file

At this stage, the information about the link and the downloaded effect algorithm only exists in the memory of the host machine and is not saved as a file. When the effect algorithm is complete, select “Save” from the File menu to save it.

● Step 9: Exit the linker application

Select “Quit” from the File menu to exit the linker application.
