RX-D702 RX-D402

*Also applies to RX-D401

At the heart of the RX-D702/D402/D401’s DSP is a new high-performance Texas Instruments DSP -- Aureus™. It’s the world’s fastest, highest-performing chip of its kind now, replacing two conventional DSP chips. The JVC receiver is the world’s first to feature this LSI.

Features

•1,800MIPS* or 1,350MFLOPS** (at 225MHz clock speed) -- one of the highest processing power ratings on the market

•32-bit (64-bit double precision) accurate operations

•Decode formats: Dolby Digital, Dolby Digital EX, Dolby Pro Logic IIx, DTS, DTS-ES, DTS 96/24, DTS NEO:6

•Functions: DAP, 3D-PHONIC, 3D Headphone, DSP Digital Equalizer, Dynamic Range Control, Bass Management

Advantages

•A single chip performing DTS 96/24 processing and DAP (Digital Acoustics Processing) with power to spare

•More accurate implementation of simulated DAP sound fields

•Compact size conducive to reduction in digital noise

•Floating-point operations for more accurate calculations with an expanded range of numbers

*FLOPS (Floating Point Operations per Second): the number of floating-point calculations per second performed with real numbers.

**MIPS (Million Instructions per Second): A 1MIPS computer processes 1 million instructions per second. An “instruction” is a command sent out to a DSP to directly control and operate it. A DSP executes instructions stored in memory, makes calculations and outputs the result. The number represents a DSP or CPU’s capability of computing -- the greater the power of processing.
