Description

The TLV320AIC15 implements the smart time division multiplexed serial port (SMARTDM™). This is TI’s design innovation to optimize DSP performance with its most advanced synchronous serial port in TDM format for glue-free interface to popular DSPs (i.e., C5x, C6x) and microcontrollers. The SMARTDM supports both continuous data transfer mode and on-the-fly reconfiguration programming mode. SMARTDM maximizes the bandwidth of data transfer between the TLV320AIC15 DSP codec and the DSP. In normal operation, it automatically detects the number of codecs in the serial interface and adjusts the number of time slots to match the number of codecs so that no time slot in the TDM frame is wasted. In the turbo mode, it maintains the same number of time slots but maximizes the bit transferred rate to 25 MHz to give the DSP more bandwidth to process other tasks in the same sampling period.
