XMOS launch of a suitable iPhone ® and iPod ® dock of the reference design, to ensure that through the USB from the iPod or iPhone ® to the amplifier's audio signal path end to end digital. Flexible design can be achieved entirely through software, through the XS1-L event -driven processor (event-driven processor ™) use, eliminating the need to prevent radio frequency ( RF ) interference of the analog audio processing components, in order to get the best insurance truth degree of audio performance to provide the perfect bit (bit-perfect) of the digital audio data stream.

32-bit digital signal processing , and one 64-bit media access control ( MAC ) combine to eliminate the rounding error, while the unique design of asynchronous local clock architecture to ensure zero clock jitter; is accurate, the whole dynamic range of sound reproduction the decisive factor.
By digital signal processor 185MIPS path and spare XMOS DSP processing power combined, designers can easily add custom digital sound enhancement to improve audio quality. Simple equalizer function and spatial orientation, such as bass boost and psychological enhancements such hearing, it can be added to a variety of third-party algorithms into being.
XMOS Joerg Bertholdt Vice President of Sales said, "iPod and iPhone, means it is a convenience for the user to save all the music the perfect space, the user can play music in various ways. Through our end digital reference design, to help us customer base of the iPod and iPhone solutions to market, it sounds great! "
The reference design uses C, XC and C + + programming language, the core XS1-L event-driven processor to provide users with a fully flexible embedded software-defined workflow. In addition to its powerful audio processing capability, the reference design also provides a variety of digital audio interfaces to choose from, including I2S, SPDIF, 1-bit software compatible digital-analog converter ( DAC ) and Pulse Width Modulation ( PWM ). And ready to support customers 'front-of-box' peripherals and control code development.
Processor firmware can also use device firmware upgrade in the future be updated at any time. To improve the service based on product updates to software and hardware to create the conditions.
For up "Made for iPod" authorization XMOS digital iPod dock reference design is available now, to ensure rapid development of products with the iPhone and the iPod line. The XMOS XS1-L1 number of event-driven processors to buy when the price of less than 5 to 10,000 dollars.
XMOS is rewriting the electronic products used in design. The revolutionary event-driven multi-core processors to create the system entirely through software easier to achieve. XMOS designers enjoy the fastest to the product from a creative way, through the use of standard procedures for designing chips that can construct a kind of interfaces can, DSP and control functions are fully integrated in the software of the complete system. For those leading electronics brand entrepreneurs, researchers and designers, XMOS innovation and achieve substantial cost reductions.
