Abstract:
A solid-state memory storage device and method for using the device includes storing data wirelessly transmitted from a host and wirelessly transmitting the data to the host. The storage device has an RF module which demodulates an ultra-wideband write signal received wirelessly from a host and outputs a wireless protocol write signal. A wireless protocol controller has a protocol conversion layer which converts the wireless protocol write signal into a USB protocol write signal. A microcontroller has function extraction layer for extracting a write command from the USB protocol write signal and, in response to the write command, controls the writing of data extracted from the USB protocol write signal to the solid-state memory to store the data in the solid-state memory. The microcontroller also reads the data stored in the solid-state memory in response to a read command received from the host and outputs a USB protocol read signal to the wireless protocol controller. The protocol conversion layer also translates the USB protocol read signal into a wireless protocol read signal. The RF module also modulates the wireless protocol read signal and outputs an ultra-wideband signal for wireless transmission to the host.

Abstract:
A removable electronic circuit card has multiple modules connected to the card’s bus in parallel so that each module can exchange commands and data independently with the host. According to a first aspect of the present invention, this achieved by a controller-to-controller interface whereby the modules can facilitate their interactions with the host. In a fist set of embodiments, the modules are on a single card, while in a second set of embodiments the modules are distributed across multiple cards, where a first card attaches to the host and other cards attach to the first card rather than directly to the host. In all of these cases, the host sees the multiple modules as a single card having a single module. In a further aspect of the present invention, the card or cards are able to communicate with the host in more than one protocol.
Abstract:
Computer and peripheral interfaces that have both wired communication and wireless communication interfaces are provided. In one implementation, one of the two communication interfaces may be activated while the other interface is inactive and is used as a backup. When the operating interface fails, control logic detects the failure and activates the backup interface to maintain the communication. In other implementations, the user can select which of the two types of communication interface is desired.
Abstract:
A PLL frequency multiplier is provided having a latency substantially equal to the wake-up time of the PLL. An operative clock signal is provided to a processor while the PLL is acquiring phase lock by insuring that the clock signal does not contain frequencies above a target frequency of a PLL and below a predetermined threshold frequency. In particular, a frquency divider and a frequency detector are provided to prevent the frequency of the clock signall from operating outside the range defined by the threshold and target frequencies.
Abstract:
A direct memory access system consists of a direct memory access controller (116) establishing a direct memory access data channel and including a first interface for coupling to a memory. A second interface is for coupling to a plurality of nodes. And a processor (106) is coupled to the direct memory access controller (116) and coupled to the second interface, wherein the processor configures the direct memory access data channel to transfer data between a programmably selectable respective one or more of the plurality of nodes and the memory (104 or 108). In some embodiments, the plurality of nodes are a digital signal processor memory and a host processor memory of a multi-media processor platform (100) to be implemented in a wireless multi-media handheld telephone.
