`
`ABSTRACT
`
`A novel personal electronic device includes a processor
`having first (embedded) and second (non-embedded) cores
`including associated operating systems and functions. In one
`aspect, the first core performs relatively limited functions,
`while the second core performs relatively broader functions
`under control of the first core. Often the second core requires
`more power than the first core and is selectively operated by
`the first core to minimize overall power consumption. Pro(cid:173)
`tocols for functions to be performed by the second core may
`be provided directly to the second core and processed by the
`second core. In another aspect, a display controller is
`designed to interface with both cores. In another aspect, the
`operating systems work with one another. In another aspect,
`the first core employs a thermal control program. Advan(cid:173)
`tages of the invention include a broad array of functions
`performed by a relatively small personal electronics device.

`
`[0001] This is a continuation in part of U.S. Ser. No.
`10/340,922 filed Jan. 13, 2003, which is a continuation in
`part of U.S. Ser. No. 10/158,266 filed May 30, 2002, which
`is a continuation in part of U.S. Ser. No. 09/809,963 filed
`Mar. 16, 2001, all incorporated herein by reference.
`
`FIELD
`
`[0002] The
`invention pertains to personal electronic
`devices in the general category of smart handheld devices,
`personal computers, mobile telephones, and the like.
`
`BACKGROUND
`
`[0003] With electronics becoming
`increasingly more
`sophisticated, a wide variety of devices has become avail(cid:173)
`able to provide users with a tool to help them manage their
`affairs and improve their ability to communicate with others
`both at work and in their personal lives. Computers are well
`known and have taken on a variety of flavors, including
`portable computers, which can be carried from place to place
`with relative convenience. Mobile telephones have come
`into widespread use due to their small size and ease of use
`and the widespread availability of cellular services in a large
`portion of the industrialized world. More recently, small
`computer-like devices with limited computational capabili(cid:173)
`ties have become popular and are often referred to as Smart
`Handheld Devices or Personal Digital Assistants (PDAs).
`Such PDAs are typically small hand held devices including
`a battery, a liquid or digital display (LCD) touchscreen, a
`small amount of memory (typically on the order of 8 to 16
`megabytes of random access memory (RAM)) and a small
`amount of computer processing capability. Given the small
`battery size and the limited memory and computational
`power, such PDAs have typically been used for contact
`management, scheduling appointments, and email. The
`common practice of a PDA user is to routinely synchronize
`his/her PDA with his/her desktop PC computer. This syn(cid:173)
`chronization requirement is awkward and time consuming to
`maintain.
`[0004] FIG. 1 is a block diagram depicting a typical prior
`art cellular telephone, including a battery, a display, a
`man-machine interface (MMI) and a cellular telephone
`module that includes radio frequency (RF) circuitry, and a
`Digital Signal Processor (DSP).
`[0005] A current trend is to include both PDA functions
`and cellular telephone functions in a single device. One such
`device is the HandSpring Visor phone system, which basi(cid:173)
`cally takes a HandSpring PDA device and a separate cellular
`telephone device mechanically attached to the PDA. This
`device is shown in a block diagram in FIG. 2A in which
`System 100 includes PDA 101 and an attached Cellular
`Telephone Module 102. Such a device is somewhat cum(cid:173)
`bersome and includes two separate batteries, a first for PDA
`101 and a second for Cellular Telephone Module 102. Since
`PDA 101 and Cellular Telephone Module 102 are connected
`by one or more external interfaces, the communication
`speeds between PDA 101 and Cellular Telephone Module
`102 are relatively limited. These devices are heavy, weigh(cid:173)
`ing approximately 10 ounces, and have a bulky form-factor,
`
`[0006] Another approach is to provide a device that serves
`as both a PDA and a cellular telephone. Such a device is
`shown by way of example in FIG. 2B and typically includes
`a Cellular Telephone Module 201 and an LCD Display 202,
`a Processor 204, and a Battery 203. This type of device
`constitutes basically an advance on cellular telephones,
`including additional features. Such devices may include the
`Kyocera pdQ Smart Phone device that combines CDMA
`digital wireless telephone technology with Palm PDA capa(cid:173)
`bilities. The pdQ Smart Phone device is essentially a tele(cid:173)
`phone that includes a pushbutton pad for making telephone
`calls. In this device, the pushbutton pad pivots out of the way
`to reveal a larger LCD screen for use with PDA functions.
`Nokia has a similar device, the Nokia 9110 Communicator,
`which appears as a basic cellular telephone including push(cid:173)
`button keys and which opens up to reveal a larger LCD
`screen and a mini-keypad with PDA functions.
`
`[0007] There are significant problems with PDAs, Internet
`Appliances (IAs) and cellular telephones. The PDA, IA and
`cellular telephone metaphors are dramatically different than
`what users expect in the personal computer (PC) world.
`They have less powerful CPUs, less memory, restricted
`power consumption, smaller displays, and different and
`awkward input devices in comparison to what is available in
`a PC. Additionally, they have a limited screen size and the
`lack of a mouse or touch screen. This requires a different
`user interface (UI) metaphor, as compared with PCs. In
`some of these devices, there are touchscreens, but the small
`display sizes make the input and display of information
`difficult and cumbersome.
`
`[0008] Two significant problems with PDAs and IAs are
`that they lack the full power of a PC and, from a price vs.
`performance perspective, the limited capabilities outweigh
`the benefits. Many PDAs are actually slave devices to PCs
`and the IAs lack the horsepower of a full-blown PC, such as
`a Pentium class PC. For this reason IAs are close enough in
`functionality to a PC that the price difference is not dramatic
`enough to warrant purchasing an IA Similarly, PDAs are
`significantly less powerful than a PC such that, even with the
`relatively large price difference, in many cases purchase of
`a PDA is not justified.
`
`[0009] A significant complaint about cellular telephones,
`PDAs and IAs is that they operate independently of one
`another. This has required the user to retain a plurality of
`devices if the user intends to provide the three functions, and
`obtain the advantages of the PDAs and the IAs. Some
`inventors have attempted to integrate the PDA and the
`cellular telephone, but these devices still lack the horse(cid:173)
`power, display and input power of a PC. Some integration
`occurs between PDAs and PCs, because, as mentioned
`earlier, PDAs are inherently slave devices to a PC. However,
`such integration offers only limited advantages.
`
`[0010] Because there will always be a performance gap
`between the very best desktop computers, PDAs, IAs and
`cellular telephones, a device is required that combines and
`consolidates these technologies in a meaningful device. This
`is the subject of the present invention.
`
`[0011] Trademarks used herein belong to their respective
`owners and are used simply for exemplary purposes.

`
`SUMMARY
`
`[0012] The invention overcomes the identified limitations
`and provides a novel personal electronic device that com(cid:173)
`bines the functionality of a cellular telephone, PDA, PC and
`IA
`
`[0013]
`In an exemplary embodiment, a first (embedded)
`processor and a second (non-embedded) processor are com(cid:173)
`bined in a handheld housing. The first processor performs a
`majority of the device's rudimentary functions and calls
`upon the second processor in order to perform more com(cid:173)
`plex functions. The device is very power efficient since the
`first processor draws less power than the second processor.
`To further enhance power efficiency, the second processor is
`normally asleep and is selectively activated by the first
`processor to perform the complex functions to satisfy the
`user's operational demands. Programs and data for operating
`the second processor flow initially into the second processor.
`The second processor processes the programs and data and
`introduces the processed information to a read-only memory
`in the first processor. When the second processor is to
`perform such programs and utilize such data, the first
`processor introduces such program and data to the second
`processor for processing by the second processor.
`
`[0014] The invention provides for one consummate hand(cid:173)
`held personal electronic device that performs a multiplicity
`of functions. Users will not need to learn a new operating
`system. There is no need for new, third party software
`development. All the applications that users are accustomed
`to running each day on their laptops or desktop computers
`can be utilized. The novel device is completely mobile,
`fitting into a shirt picket, a purse or the palm of one's hand.
`The device utilizes a single power source (e.g. one battery)
`for two processors, a first one an embedded processor that
`performs simple functions and a second one a non-embed(cid:173)
`ded processor that performs relatively complicated functions
`and utilizes increased amounts of power. The second pro(cid:173)
`cessor is normally inactivated and is activated when the first
`processor determines that the second processor should per(cid:173)
`form these functions.
`
`[0015]
`In one embodiment, the processors described
`above are cores integrated into a single integrated circuit
`processor. In such an embodiment, the structure and func(cid:173)
`tions of the embedded core and non-embedded cores are
`substantially the same as the described processors. However,
`since they are commonly integrated in one processor inte(cid:173)
`grated circuit, they share some components and reduce the
`overall device chip count, thereby improving the efficiency
`and power conservation of the device.
`
`[0016]
`In another embodiment, the embedded processor,
`the embedded processor is configured to operate a keypad
`control program that includes a set of application protocols
`that enable the display using a keypad software application.
`In another embodiment, the invention includes a display
`switching circuit that enables the display to receive and
`accurately render information on the display from the
`respective processors. In another embodiment, the invention
`includes a display technology that is a novel size. In another
`embodiment, the invention includes a novel technique for
`controlling the temperature of the device and dissipating
`unwanted heat. In yet another embodiment, the invention
`includes a common application platform that establishes
`new protocols and interfaces between two operating sys-
`
`terns. In various embodiments, the invention can also be
`configured as an appliance drive that communicates with
`another computer, for example, a standard type personal
`computer.
