Function Documentation

◆ dmaKit_get_spr()

void dmaKit_get_spr ( u16 channel,
void * data,
void * dest,
u32 size )

DMA Get from Scratchpad Routine Transfers data from an external source to the EE. (ex: Scratchpad -> EE Main Memory)

Definition at line 214 of file dmaCore.c.

◆ dmaKit_send()

void dmaKit_send ( u16 channel,
void * data,
u32 size )

DMA Send Routine Standard DMA send routine.

Definition at line 56 of file dmaCore.c.

◆ dmaKit_send_chain()

void dmaKit_send_chain ( u16 channel,
void * data,
u32 size )

DMA Chain Send Routine Sends data over the DMAC using a DMA Chain.

Definition at line 135 of file dmaCore.c.

◆ dmaKit_send_chain_spr()

void dmaKit_send_chain_spr ( u16 channel,
void * data )

DMA Chain Scratchpad Send Sends data over the DMAC using a DMA Chain via the scratchpad.

Definition at line 189 of file dmaCore.c.

◆ dmaKit_send_chain_ucab()

void dmaKit_send_chain_ucab ( u16 channel,
void * data )

DMA Chain UCAB Send Sends data which has been written to RAM using UCAB over the DMAC using a DMA Chain.

Definition at line 163 of file dmaCore.c.

◆ dmaKit_send_spr()

void dmaKit_send_spr ( u16 channel,
void * data,
u32 size )

DMA Scratchpad Send Routine Similar to dmaKit_send, but reads from the scratchpad instead.

Definition at line 110 of file dmaCore.c.

◆ dmaKit_send_ucab()

void dmaKit_send_ucab ( u16 channel,
void * data,
u32 size )

DMA UCAB Send Routine Similar to dmaKit_send, but for UCAB data pointers.

Definition at line 84 of file dmaCore.c.

◆ dmaKit_wait()

int dmaKit_wait ( u16 channel,
u32 timeout )

DMA Wait Routine This routine checks and waits for the DMAC to become free. The other routines in dmaKit use this to know when it's clear to send data over the DMAC.

Definition at line 19 of file dmaCore.c.

◆ dmaKit_wait_fast()

void dmaKit_wait_fast ( void )

DMA Fast Wait Routine This routine does the same as above, but using an accelerated EE instruction method rather than register polling. The channels argument takes a bitmask of the channels you want to wait for.

Definition at line 45 of file dmaCore.c.
