CONFIDENTIAL ADVANCE INFORMATION Analog Reinvented Crescendo II SoundBar SoC Product Brief The Crescendo II SoundBar is an SoC targeted for TV soundbar applications. To enable the lowest system BOM cost, the Crescendo II SoundBar employs a unified memory architecture and integrates all TV soundbar processing functions in a 128-pin Low Profile Quad Flat Pack (LQFP) package. The Crescendo II SoundBar’s core A/V decoder is built on the ESS proprietary dual CPU Programmable Multimedia Processor (PMP) core consisting of 32-bit RISC and 64-bit Media Processor that deliver the best soundbar feature set. In addition, the Crescendo II SoundBar integrates an audio postprocessing DSP for sound effect processing such as virtual surround or stereo expansion. The Crescendo II SoundBar integrates a hardware parametric equalizer for speaker equalization, a 5.1ch Hyperstream™ PWM or D/A converters to deliver the best sound via digital or analog power amplifiers, a 2-input SPDIF receiver, a 3-input audio ADC for connection to line-in sources an 8channel I2S input for connection to HDMI repeater or Blu-ray processor, remote and GPIO handlers for buttons and LEDs, and a FS USB 2.0 host controller for firmware upgrade at the field or music playback from thumb drives or iPod.
