Audio
Today, consumers demand Hi-Fi quality, multi-function, feature-rich audio products in a small form factor and at a low price. This presents a challenge to IC designers and audio device manufacturers in finding high-performance, ultra low-power audio analog content at low risk. Until now, this functionality has only been available on standalone chips at high price points, or on discrete, non-optimized analog IP components that pose integration difficulties along with increased risk, time-to-market and cost.
Audio processing is essential to mobile phones, portable media players (PMP, MP3, etc.); digital cameras; camcorders; CD, DVD and Blu-ray DiscTM recorders; HDTV; set-top boxes; toys; and a host of other electronic products where size and power consumption are critical design criteria. Additionally, advanced portable products such as GPS navigation devices and smart phones need to set themselves apart from similar products by adding value with audio capabilities, continuously creating an expanding marketplace for audio processing.
To address this market, MIPS Technologies offers the most complete family of portable, easy-to-integrate and low-risk audio IP on the market. This includes the most advanced high-performance, low power and compact Hi-Fi audio technology, enabling advanced audio functions like Class-D/G drivers, parametric equalization and automatic level control usually only available in costly standalone ICs.
MIPS' audio solutions are backed by a dedicated team with more than 10 years of proven experience with millions of ICs in mass production.
