System On A Chip With Rtc Power Supply

View page
US Patent:
7882383, Feb 1, 2011
Filed:
Apr 25, 2007
Appl. No.:
11/789763
Inventors:
Marcus W. May - Austin TX, US
David A. Dyches - Round Rock TX, US
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
G06F 1/00
G05F 1/00
US Classification:
713500, 713300, 323280, 323281
Abstract:
A system on a chip includes a real time clock (RTC) module, a crystal oscillation circuit and a voltage supply circuit. The RTC module is coupled to provide timing functions and the crystal oscillation circuit is coupled to produce an oscillation. The voltage supply circuit is coupled to produce a supply voltage for at least a portion of the RTC module and the crystal oscillation circuit. The voltage supply circuit includes: a reference circuit coupled to produce a reference voltage based on the supply voltage; a transistor coupled to the battery IC pin, wherein the transistor produces the supply voltage based on a regulation signal and the battery voltage; an amplifier coupled to produce the regulation signal based on the reference voltage and a feedback representation of the supply voltage; and a start-up circuit coupled to enable the voltage supply circuit at battery connection.

Method And Apparatus For Determining Simple Convex Polygons

View page
US Patent:
63042703, Oct 16, 2001
Filed:
Jul 17, 1996
Appl. No.:
8/682419
Inventors:
Brian H. Danielson - Tomball TX
David A. Dyches - Spring TX
Assignee:
Compaq Computer Corporation - Houston TX
International Classification:
G06T 1120
US Classification:
345433
Abstract:
An accelerated video controller operates in conjunction with a video driver to accelerate certain video operations. If the operating environment requests a polygon operation, the driver (or software on the video controller) will determine whether the specified polygon is simple convex. The determination of whether a convex polygon is simple convex is accomplished by tracing between the vertices of the polygon and comparing the changes in direction relative to a predetermine coordinate axis to a threshold number. If the polygon is simple convex, certain operations can be performed using simpler code or hardware accelerated features. For a polygon fill, if the polygon is simple convex, the edges of the polygon are inspected to determine whether the polygon can be decomposed into a rectangle and a smaller polygon. If so, the video controllers bit engine will be used to perform the fill of the rectangle at high speed, thus reducing the time of the operation.
