16 Bits DSP Sound Processor
1 General Description
The ELAN eSLS Series IC is a 16-bit DSP Sound Processor with multi-channel
speech and instrument playback. It is based on ELAN 16-bit DSP platform. The
series has a powerful 16-bit DSP architecture that handles most of the speech/
melody functions. Speech and melody can be played back simultaneously. The
speech synthesis is implemented by software and supports a wide range of
compression bit rates and various volume levels. The ELAN eSLS Series provides
real instrument waveform to obtain good quality melody. The ELAN eSLS peripheral
includes RTC, Timer, WDT, DAC, PWM, etc.
The ELAN eSLS Series IC’s offer Fast mode, Sleep mode, Green mode, and Slow
mode of operation. The use of Green/Slow mode will further reduce the power
consumption. Green mode also provides RTC function for wake-up purposes.
The ELAN eSLS Series enhanced features make it suitable for versatile voice and
sound effect product applications. These enhanced versatile features allow users to
create products with a wide variety of new fancy ideas.
The ELAN eSLS Series have extreme high performance in speech application based on
powerful DSP architecture and good algorithm in audio compression.
