Hardware experiments in the DSP lab are performed on the Texas Instruments (DSK) TPS320C6713 DSP Boot Kit, based on the floating point DSP TMS320C6713 running at 225 MHz. The basic clock cycle instruction time is 1 / (225 MHz) = 4.44 nanoseconds. During each clock cycle, up to eight instructions can be performed in parallel, achieving up to 8 × 225 = 1800 million instructions per second (MIPS). The C6713 processor has 256KB of internal memory, and potentially can handle 4GB of external memory. The DSK card includes a 16MB SDRAM memory and a 512KB Flash ROM. It has a 16-bit stereo audio encoder (the Texas Instruments AIC23B) that serves as an A / D and D / A converter. There are four 3.5mm audio jacks for microphone and stereo line input, and speaker outputs and headphones.
The AIC23 codec can be programmed to sample audio inputs at the following sample rates:
fs = 8, 16, 24, 32, 44, 48, 96 kHz.
