The Macintosh Quadra 840AV combines the raw horsepower of a
 +
40-megahertz 68040 microprocessor with a 66-megahertz digital signal
 +
processor (DSP) to achieve outstanding performance. The DSP handles
 +
telecommunications, speech, and audio functions, allowing the 68040
 +
processor to perform other tasks, thereby increasing the total system
 +
performance.
 +
 +
The exceptional power and built-in features of the Macintosh Quadra
 +
840AV let you take full advantage of exciting new audio-visual
 +
technologies. For example, with its built-in GeoPort
 +
telecommunications architecture, the Macintosh Quadra 840AV can be
 +
connected with telephone systems, so you can use your computer as a
 +
telephone, an answering machine, a fax machine, and an electronic mail
 +
station. Its video capabilities let you view or capture video from a
 +
VCR, laser disc, or camcorder in a window. You can also connect
 +
directly to a TV to show your presentations or to a VCR to make
 +
videotapes.

The Macintosh Quadra 840AV and Macintosh Centris 660AV computers include an AT&T DSP3210 32-bit floating-point digital signal processor (DSP). The DSP gives these computers the ability to perform fast, complex real-time data processing tasks, such as speech recognition, audio compression, analog modem signal processing, and so on. In the Macintosh Quadra 840AV, the DSP runs at 66.6667 MHz; in the Macintosh Centris 660AV, it runs at 55.5000 MHz. The DSP chip contains its own 8 KB of internal RAM, which minimizes its use of system memory.
