1) Preparation of data necessary for calculation (LDI / LDY / LDA) 2) Description of multiply-add formula (@ ...) 3) Specify the store location (>)
Considering the above procedure as one unit process, an appropriate partial function is extracted from the signal flow diagram and applied to this unit process to describe the partial source code. The source code is described by repeating this in the order of processing.
The following explains how to code DSP programs in dAsms, using relatively simple examples.
In the following program example, external extended inputs EXTS00 and EXTS01 that can be input by CD Audio etc. are input to Lch and Rch respectively, and the result of delay (echo) processing performed independently for Lch and Rch will be output to EFREG00 and EFREG01, respectively. It is what.
