Development Tool System

- Program development flow -

Development tools are provided to help the user to easily

develop application programs for the D2SP. These

development tools are divided into two groups: software

support tool group and hardware support tool group. The

software support tool group consists of an assembler,

debugger and simulator.

The hardware support tool group is realized as an In-

Circuit Emulator (ICE).

Figure A-3 shows the applications development flow for

the D2SP system.

(1) Write an application source program.

(2) Check the source program for syntax errors with the

assembler. If every syntax error is corrected, the

assembler generates a HEX program file.

(3) Check the HEX file for operational errors with the

simulator. If the desired operations are not successful,

start the debugger to find what caused logical errors.

(4) If program operations are checked successfully, use

the ICE to evaluate the audio signal output.

First, evaluate sound signals only with the ICE. In this

evaluation process, the delay memory and microcom-

puter of the ICE are used.

Second, start the total evaluation on an application

system. In this evaluation stage, the AD/DA convert-

ers, microcomputer, and delay memory on the user

application system are used.

Figure A-4 shows the entire program development

tool system for the D2SP.

The software tools such as the assembler, debugger,

simulator can be run on an IBM PC-AT compatible

machine or an AX personal computer. The ICE is also

controlled by such a host personal computer.
