A high density non-volatile memory system, card, and device is described that incorporates a synchronous interface. This is accomplished through use of an external or embedded controller and/or memory buffer to manage the high density non-volatile memory device(s) to present it as a conventional memory device having a synchronous interface that is accessible by row and column address. This allows the high density non-volatile memory to support in-place code execution and allows it to be booted from. Additionally, this incorporation eliminates the overhead of drivers and/or operating system support required to utilize and present conventional high density non-volatile memory devices and moves it internal to the memory device. This simplifies the use and design effort in the overhead and specialized interfacing of high density non-volatile memories and in particular, NAND architecture Flash memories, while reducing the production cost through use of less expensive high density non-volatile memory.

In order to overcome the relatively short battery life and the relatively long delay between the activation and the actual functioning of a typical mobile computing system, the mobile computing system is provided with a personal computer (PC) architecture system and a personal digital assistant (PDA) architecture system, and a common display and shared peripherals. Interfacing to the systems is a super input output or embedded controller (SIO/EC) that acts as a slave device to whatever system has control of computing system. The SIO/EC controls a quick switch which blocks or allows communication along communication busses connecting the systems to the SIO/EC. A user can selectively change, by way of a user interface to the SIO/EC, to whatever system that is desired by the user.

The present invention provides a very flexible, digital system for capturing and storing panoramic images using progressive scan (that is, non interlaced) technology. The system includes a digital image input device and an associated control computer. Since the image capture device is digital it can be easily and flexibly controlled by software in the control computer. The image input device has six lenses positioned on the six faces of a cube. While the image input system can have other lens configurations, the use of six lenses in a cubic configuration is optimal for a system that is used to capture a spherical panorama. The six lenses simultaneously focuses different images on six CCDs (Charge Coupled Devices). The image input device also includes an embedded controller, and data compression circuitry. The embedded controller controls the exposure time of the CCDs (i.e. the effective aperture and effective shutter speed) and reads image data from the CCDs. The image data read from the CCDs is compressed, multiplexed, and sent to the control computer. The control computer stores the images in frames, each of which have one image from each of the six lenses. Each frame includes six images that were simultaneously recorded and any associated information, such as audio tracks, textual information, or environmental information such as GPS (Global Position System) data or artificial horizon data. The control computer includes a user interface which allows a user to specify control information such as frame rate, compression ratio, gain, etc. The control computer sends control information to the embedded controller which in turn controls the CCDs and the compression circuitry. The images can be sent from the control computer to a real time viewer so that a user can determine if the correct images are being captured. The images stored at the control computer are later seamed into panoramas and made into panoramic movies.
