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.

A storage target device controller (such as an embedded controller in a SCSI disk drive) processes multiple commands concurrently in accordance with the methods and structures of the present invention. Each command is stored within its own context within the target device controller to retain all unique parameters required for the processing of each command. Processing of multiple commands permits switching of command contexts within the target device to improve utilization of resources associated with the target device. For example, when a first, active, command context is prevented from further processing due to the status of the disk channel, an inactive command context may be swapped with the active command context to better utilize the host channel communication bandwidth. Similarly, a first active command context may be configured to automatically switch to a linked command context upon completion of processing to further ease management of multiple contexts. In a preferred embodiment of the present invention, a set of registers contain the active context while a second set of registers contains an inactive command context. The sets of registers are configured in such a way that the active and inactive context may be rapidly switched with no intervention by the microprocessor. The inactive register set may be read or written directly by the microprocessor, or may be automatically loaded / stored from / to a buffer memory in the target device by shifting a predetermined context structure into the inactive register set through an interface pad with the buffer memory.

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.

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.
