11.8. System Design with the Diamond 330HiFi audio DSP Core
Figure 11.8 shows a simple stereo audio system that uses the Diamond 330HiFi audio engine’s queue output to create a low-overhead, dual 16-bit interface to the system’s audio DACs. The DSP can output a value to the two audio DACs in one cycle, which greatly reduces the I/O overhead associated with the operation. Because the audio DACs are essentially “ready” all the time, the Diamond 330HiFi can use this single-wire handshake mechanism to the audio DACs.
