GENERAL DESCRIPTION
6/47
Issue 1.6
color space converter (RGB to 4:2:2 YCrCb) to the
programmable anti-flicker filter. The flicker filter is
configured as either a two line filter with gamma
correction (primarily designed for DOS type text)
or a 3 line flicker filter (primarily designed for Win-
dows type displays). The flicker filter is optional
and can be software disabled for use with large
screen area’s of video.
The Video output pipeline of the STPC Client in-
terfaces directly to the external digital TV encoder
(STV0119). It takes a 24 bit RGB non-interlaced
pixel stream and converts to a multiplexed 4:2:2
YCrCb 8 bit output stream, the logic includes a
progressive to interlaced scan converter and logic
to insert appropriate CCIR656 timing reference
codes into the output stream. It facilitates the high
quality display of VGA or full screen video streams
received via the Video input port to standard
NTSC or PAL televisions.
The STPC Client core is compliant with the Ad-
vanced Power Management (APM) specification
to provide a standard method by which the BIOS
can control the power used by personal comput-
ers. The Power Management Unit module (PMU)
controls the power consumption by providing a
comprehensive set of features that control the
power usage and supports compliance with the
United States Environmental Protection Agency’s
Energy Star Computer Program. The PMU pro-
vides following hardware structures to assist the
software in managing the power consumption by
the system.
- System Activity Detection.
- 3 power-down timers detecting system inactivity:
- Doze timer (short durations).
- Stand-by timer (medium durations).
- Suspend timer (long durations).
- House-keeping activity detection.
- House-keeping timer to cope with short bursts
of house-keeping activity while dozing or in stand-
by state.
- Peripheral activity detection.
- Peripheral timer detecting peripheral inactivity
- SUSP# modulation to adjust the system per-
formance in various power down states of the sys-
tem including full power on state.
- Power control outputs to disable power from dif-
ferent planes of the board.
Lack of system activity for progressively longer
period of times is detected by the three power
down timers. These timers can generate SMI in-
terrupts to CPU so that the SMM software can put
the system in decreasing states of power con-
sumption. Alternatively, system activity in a power
down state can generate SMI interrupt to allow the
software to bring the system back up to full power
on state. The chip-set supports up to three power
down states: Doze state, Stand-by state and Sus-
pend mode. These correspond to decreasing lev-
els of power savings.
Power down puts the STPC Client into suspend
mode. The processor completes execution of the
current instruction, any pending decoded instruc-
tions and associated bus cycles. During the sus-
pend mode, internal clocks are stopped.
remov-
ing power down, the processor resumes instruc-
tion fetching and begins execution in the instruc-
tion stream at the point it had stopped.
A reference design for the STPC Client is availa-
ble including the schematics and layout files, the
design is a PC ATX motherboard design. The de-
sign is available as a demonstration board for ap-
plication and system development.
The STPC Client is supported by several BIOS
vendors, including the super I/O device used in
the reference design. Drivers for 2D accelerator,
video features and EIDE are availaible on various
operating systems.
The STPC Client has been designed using mod-
ern reusable modular design techniques, it is pos-
sible to add to or remove the standard features of
the STPC Client or other variants of the 5ST86
family. Contact your local STMicroelectonics sales
office for further information.
