7.2.1 Functional Overview of DSK 6713

The DSP on the 6713 DSK interfaces to on-board peripherals through a 32-bit wide

EMIF (External Memory Interface). The SDRAM, Flash and CPLD are all connected to the bus.

All addresses are 32 bits wide. Portions of the internal memory can be reconfigured in software

as L2 cache rather than fixed RAM. The DSP interfaces to analog audio signals through on-

board TLV320AIC23 codec and 3.5mm audio jacks (microphone input, line input, line output

and headphone output). The codec can select the microphone input (monaural input) or the line

input (stereo input) as active input. The analog output is driven to both the line out (fixed gain)

and headphone/speaker out (adjustable gain) connectors. The codec communicates using two
