Description
Summary:This paper presents an implementation of portable sound effector using the tiny packaged sound effect module which includes implemented sound effects, sound effect SoC, and EEPROM. The SoC integrates the embedded DSP core, an audio codec, some peripheral blocks, and various sound effect algorithms where cost savings made by reducing the chip count and size. In the implementation of sound effect algorithms, we employ the primitive functions of the DSP compiler, which provide an efficient way to optimize the compiled code. This portable sound effector is developed as an all-in-one product for the low cost and high portability.
