Member Function Documentation

void Frz::CellGfx::in_mbox_write	(	int	i,
		uint32_t *	array,
		int	count
	)			[protected]

Writes a set of 32-bit integers to the inbound mailbox of a specified SPE thread.

Parameters:

	i	SPE thread number (between 0 and SPE_COUNT-1).
	array	Pointer to the first element in the integer array.
	count	Number of elements to be written.

uint32_t Frz::CellGfx::out_intr_mbox_read

(

int

i = 0

)

[inline, protected]

Reads a 32-bit integer from the interrupt outbound mailbox of a specified SPE thread.

If no value is available, the current thread waits for a value to become available.

Parameters:

i

SPE thread number (between 0 and SPE_COUNT-1).

Returns:

the read value.

uint32_t Frz::CellGfx::out_mbox_read

(

int

i

)

[inline, protected]

Reads a 32-bit integer from the outbound mailbox of a specified SPE thread.

Parameters:

i

SPE thread number (between 0 and SPE_COUNT-1).

Returns:

the read value or zero if no value is available.

int Frz::CellGfx::out_mbox_status

(

int

i

)

[inline, protected]

Returns the status of the outbound mailbox of a specified SPE thread.

Parameters:

i

SPE thread number (between 0 and SPE_COUNT-1).

Returns:

the number of elements to be read in the mailbox.
