DESCRIPTION
This device is a high-performance, fully program-
mable DSP, suitable for a wide range of applica-
tions and particularly for Audio and Sound Proc-
essing. It contains a 24-bit 50 MIPS DSP core,
several interfaces for control and data, plus a

configurable PLL.
The computational power and the memory con-
figuration make this device particularly suitable
for in car equalisation. This device will offer the
best trade-off between performance and cost
when coupled with the TDA7531, or other de-
vices of the same family. A library of sound proc-
essing functions is available for this device; some
of these functions are: parametric equaliser,
cross over filters, acoustic delay, dynamic com-
pression, Vol/Bass/Treble/Fader, active equalisa-
tion, Stereo Spatial Enhancement.
