25.7 Automotive, Industrial<br />

Although it is often forgotten when discussing advanced digital developments, the automotive industry<br />

could be the surprise of the decade for the DSP industry.<br />

Engine Control<br />

Due to history and real-time constraints, the automotive industry uses the principle of table interpolation<br />

for engine control; however, the availability of faster CPUs and the development of sophisticated algorithms<br />

could change that in favor of more “classical” DSP techniques. In fact, automotive could become<br />

the first embedded mass-market where floating-point DSP is implemented.<br />

Navigation Platform<br />

GPS/navigation: In automotive, GPS is part of the dashboard platform. How big will this market be?<br />

Industrial<br />

A large application found in the industrial market segment is motor control. Quite a very different control<br />

from car engine control, the two applications are strongly related since they are the domain of microcontrollers.<br />

Identically to engine contol above, motor control is fast becoming a big DSP application.<br />

25.8 Others<br />

To finish, small many promising applications using DSP as their bases for new or more advanced features<br />

include:<br />

White appliances: Refrigerators, washing machines, or any equipment requiring closed control will<br />

eventually be heavy DSP users.<br />

Biomedical: A good example is the processing of image in medical equipment such as scanner.<br />

Audio aids: This is a much larger application than previously thought. Gene FRANTZ [2] made a<br />

parallel between visual aids (glasses) and audio aids. Let us imagine the size of the market if everybody<br />

was wearing a hearing aid to cancel noise and unwanted conversation.<br />

Biometrics: All recognition methods (fingerprint, retina, voice, etc.) rely on DSP.<br />

25.9 Conclusions: General Trends<br />

The time when a single application was driving DSP is finished. The next DSP application goal is now<br />

several thousands of DSP MIPS, and many applications are driving it:<br />

• Smart and multiple antennae techniques in wireless base stations<br />

• Third generation cellular wireless phones, smart-phones, and terminals<br />

• Broadband access devices (VDSL modem, wireless broadband, gigabit Ethernet)<br />

• Multi-channel application of the telecommunication infrastructure (typically: voice-over-broadband<br />

gateway).<br />

• Multimedia home gateways, integrated access device (IAD), wireless Home/LAN access devices<br />

• Streaming media devices (could be a MPEG4 player connected by Bluetooth to a home gateway)<br />

• HDTV, high resolution cameras, 3D audio<br />

Finally, even if no “broadband” applications existed, people would use DSP for cost reasons. When a<br />

very good sensor is needed, an imperfect sensor is a worthless commodity. By using DSP techniques<br />

(interpolation, adaptive behavior, etc.) a worthless commodity can be turned into a production device.<br />
