	Removal point offset (in bytes)

uint32	size
	Queue size (in bytes)

Detailed Description

SH4-to-AICA command queue.

Command queue; one of these for passing data from the SH-4 to the AICA, and another for the other direction. If a command is written to the queue and it is longer than the amount of space between the head point and the queue size, the command will wrap around to the beginning (i.e., queue commands can be split up).
