YSS920B
EVE
32-bit DSP Engine for Various sound Effects
YSS920B CATALOG
CATALOG No.: LSI-4SS920B21
2006.8
Outline
YSS920B is a 32-bit digital signal processor exclusively designed for sound field processing. As a
post-processing DSP after surround sound decoding, YSS920B can process various sound fields such as
various simulation surround and virtual surround through user programs, which can provide wide
variation of sound field effects on audio equipments.
Features
YSS920B has following features:
Basic compatibility with the SubDSP section of YSS922/932 for DSP program
High precision processing by 32-bit floating-point operation
Capability to process various sound effects by downloading external programs to the built-in RAM
16 channels processing capability (input: 16ch, output: 16ch)
Zero data detecting function on each channel
32-bit data transmission ability between multiple YSS920Bs
Connectability to most types of ADC, DAC and DIR through control register setting
Built-in delay memory with 32 bits × 1024 words (Max. 21.3 ms at fs = 48 kHz)
