5 / 51 page GENERAL DESCRIPTION 5/51 Release B This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. The Video output pipeline of the STPC Consumer- S interfaces directly to the internal digital TV en- coder. 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 progres- sive to interlaced scan converter and logic to in- sert appropriate CCIR656 timing reference codes into the output stream. It facilitates the high quality display of VGA or full screen video streams re- ceived via the Video input port to standard NTSC or PAL televisions. The digital PAL/NTSC encoder outputs interlaced or non-interlaced video in PAL-B,D,G,H,I PAL-N, PAL-M or NTSC-M standards and “NTSC- 4.43” is also possible. The four frame (for PAL) or 2 frame (for NTSC) burst sequences are internally generated, subcar- rier generation being performed numerically with CKREF as reference. Rise and fall times of syn- chronisation tips and burst envelope are internally controlled according to the relevant ITU-R and SMPTE recommendations. Video output signals are directed to four analog output pins through internal D/A converters giving, simultaneous R,G,B and composite CVBS out- puts. IDE INTERFACE An industry standard EIDE (ATA 2) controller is built into the STPC Consumer-S. The IDE port is capable of supporting a total of four devices. POWER MANAGEMENT The STPC Consumer-S core is compliant with the Advanced Power Management (APM) specifica- tion to provide a standard method by which the BIOS can control the power used by personal computers. The Power Management Unit module (PMU) controls the power consumption 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. - Three power down timers. - Doze timer for detecting lack of system activity for short durations. - Stand-by timer for detecting lack of system activ- ity for medium durations - Suspend timer for detecting lack of system activ- ity for 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 for detecting lack of peripheral activity - SUSP# modulation to adjust the system perform- ance in various power down states of the system 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 Power down puts the STPC Consumer-S into sus- pend mode. The processor completes execution of the current instruction, any pending decoded in- structions and associated bus cycles. During the suspend mode, internal clocks are stopped. Re- moving power down, the processor resumes in- struction fetching and begins execution in the in- struction stream at the point it had stopped. Be- cause of the static nature of the core, no internal data is lost. |
