CONFIDENTIAL ADVANCE INFORMATION Ensemble II SoC Product Brief Analog Reinvented The Ensemble II SoC is targeted for BD home theater and TV soundbar applications. To enable the lowest system BOM cost, the Ensemble II SoC employs a unified memory architecture and integrates all BD home theater and TV soundbar processing functions in a 128-pin Low Profile Quad Flat Pack (LQFP) package. The Ensemble II SoC’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 home theater and soundbar feature set. In addition, the Ensemble II SoC integrates an audio postprocessing DSP for sound effect processing such as virtual surround or stereo expansion. The Ensemble II SoC integrates a hardware parametric equalizer for speaker equalization, a 7.1ch 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, a stereo MIC ADC for connection to microphones, an 8-channel 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.
