V ideo Buffer Control reg isters
The ZR36506 uses a pre-defined SDRAM space to store the output video data before being
transferred to USB; this buffer is called Video Buffer, and is used as a FIFO which observes data
bursts at the video frame rate (up to 30 Hz) and supplies data bursts at the USB frame rate (1000
packets per second).
The size of the video buffer is set by the host computer via the SDRAM registers. Depending on
USB bandwidth and output frame size and rate, this buffer may become full in the middle of
video streaming. In this case, additional frames will be dropped by the ZR36506 until enough
free space is available in the buffer. When operating in Compressed mode, the host computer can
alter the compression rate by modifying some threshold registers on the fly. This may prevent
most "buffer-full" events and allows for consistent frame-rate (i.e. frames are not dropped). To
enable the host computer to monitor the status of the video buffer and control frame-dropping,
the ZR36506 provides the following registers:
Parameter
Register
Address
Usage
BUF_THR [9..0]
Reg.48/d7-d0
Reg.49/d4-d3
Minimum remaining buffer space to begin
frame dropping (in 2 Kbyte units). "Buffer-
Full" occurs when remaining buffer space is
less than the value in this register. The host
computer sets this register according to the
maximum space that a video frame may
occupy.
VID_BUF_LEFT
[9..0]
Reg.62/d7-d0
Reg.65/d1-d0
This is a read-only register that provides the
actual remaining buffer space (in 2 Kbyte
units). The host computer can prevent
"Buffer-Full" occurrence by monitoring this
register and changing compression
thresholds.
LFP [19..0]
Reg.63/d7-d0
Reg.64/d6-d0
Reg.65/d3-d2
This is a read-only register that provides the
SDRAM address for data write in the video
buffer at the end of every video frame (in 16
byte units). The host computer can keep track
of the current compression rate by
monitoring this register from time to time.
