SAA7712H Sound Effects DSPThe SAA7712H provides for digital signal processing
power in TV systems and home theatre systems.
A DSP core is equipped with digital inputs and outputs, a
5-band parametric equalizer accelerator, a digital
co-processor Interface and a Delay Line memory. This
architecture accommodates on-chip standard sound
processing, incredible surround, Dolby Pro Logic Surround
and other surround sound processing algorithms.
The architecture also supports co-processing, e.g. to add
to the processing power of the internal DSP core or for
multi-channel surround decoding.
All settings and parameters are controlled by an IC-bus
Interface The available Interfaces support a high
application flexibility.
The DSP core communicates over 32 dedicated Registers
The selected digital input is master for the data rate of the
DSP core. This input CAN be selected among 2 slave
IS-bus inputs. The 4 outputs from the core are passed
through 4 DACs and then routed to 4 output pins.
Two master IS-bus outputs and two master IS-bus
inputs CAN serve as an IS-bus co-processor Interface
Eight of the remaining Registers are used for
Communication with the hardware equalizer, and eight for
Communication with the Delay Line memory.
All IS-bus inputs and outputs support the Philips IS-bus
format as well as 16, 18 and 20-bit LSB-justified formats.
