AXSetMaxDspCycles

C Specification

#include <revolution.h>

#define AX_DSP_CYCLES_PBSYNC    2000
#define AX_DSP_CYCLES           (OS_BUS_CLOCK / 400) - AX_DSP_CYCLES_PBSYNC

void AXSetMaxDspCycles(u32 cycles);

Arguments

cycles Maximum DSP cycles for audio processing per frame. For a 121.5-MHz DSP, the maximum number of available cycles per 3-millisecond audio frame is 607,500.

Return Values

None.

Description

AXSetMaxDspCycles() specifies the maximum number of DSP cycles that AX may use per frame. The maximum value and default setting is AX_DSP_CYCLES.

For every audio frame, AX calculates the estimated number of DSP cycles needed to process the active voices. The number of cycles needed by a voice depends on the properties (or "complexity") of that voice.
