3-2 Hardware Process


3-2-1 CPU Process

• Construct the audio command list in RDRAM for waveform synthesis.
• Transfer the audio command list and audio microcode to the RSP.
• Transfer the waveform data (linear PCM) from the RSP to RDRAM to the AI.

• Execute the microcode transferred from RDRAM.
• Accept the audio command list in RDRAM and synthesize the waveform data.
• Transfer the synthesized waveform data to the audio buffer in RDRAM.

Figure 3-2-1 The audio data process



3-2-3 AI Process


The AI process transfers the waveform data from the audio buffer to the audio DAC (digital-to-analog converter).



3-2-4 Audio DAC Process


In the audio DAC, the digital waveform data is converted to an analog audio signal and output.
