摘要： A current boost circuit acts as an "eye opener" for a digital bus line. A controlled current injects a fraction of the normal signaling current magnitude from a source driver onto the bus line, after a transition between the two logical states on the bus line is detected. The duration of the additional current injection is a fraction of the unit interval. In one embodiment, a linear system uses the summation of a proportional boost current and a delayed and negated proportional boost current. In another embodiment, a positive or negative edge detection circuit triggers a monostable pulse generator that controls the injection of short bursts of additional current into the bus lines. In some embodiments the boost current is suppressed when the bus line is driven from a driver other than the source driver.

摘要： An Accelerated Storage Controller (ASC) (18) in an electronic device (10) allows both conventional (slower) application processor (12) to memory interfaces (14) to be employed transparently to existing software, while also allowing software configuration to realize an accelerated storage architecture on demand. Some use cases for the electronic device (10) do not require accelerated storage, and a bypass mode does not require any modification to existing software. Other use cases (such as fast download of multiple gigabytes of media) benefit from an accelerated storage architecture offloading transfer from the electronic device application processor (12), but could also work with the traditional processor (12) to memory interface (14), at the cost of slower downloads. Embodiments of the present invention provide for both these possibilities in a software-configurable architecture. Furthermore, a number of other connectivity options are provided under software control to optimize performance and connectivity for different use case scenarios.
摘要翻译：在电子设备（10）中的加速存储控制器（ASC）（18）允许传统的（较慢的）应用处理器（12）到存储器接口（14）被透明地应用于现有软件，同时还允许软件配置来实现加快存储架构的需求。电子设备（10）的一些用例不需要加速存储，旁路模式不需要对现有软件进行任何修改。其他用例（例如快速下载多千兆字节的媒体）受益于从电子设备应用处理器（12）卸载传输的加速存储架构，但是也可以与传统处理器（12）一起工作到存储器接口（14），以较慢的下载为代价。本发明的实施例在软件可配置架构中提供这两种可能性。此外，在软件控制下还提供了许多其他连接选项，以优化不同用例场景的性能和连接性。

摘要： A collaboration request may be sent to a host or a peripheral when a job is to be processed. The job may include one or more tasks. The host determines which device is better suited to act as host by analyzing the type of task or job to be executed and the capabilities of the host and peripheral. If the peripheral is better suited to act as host, the host and peripheral swap roles and control of a task or job is transferred to the peripheral. The host and peripheral may return to their default roles once the task or job is complete.

摘要： A pull-up circuit comprises an operational amplifier which forms part of a feedback circuit, acting to bring a pull-up circuit output equal to a reference voltage input. The pull-up circuit may form part of a USB transceiver for incorporation in a USB Device. When the supply voltage of the USB Device is sufficiently high, it is used to provide the required pull-up voltage, with the feedback circuit including the operational amplifier being enabled only when the supply voltage of the USB Device is not high enough to provide the required pull-up voltage. In that case, the USB bus voltage is used to generate the reference voltage which is used as an input to the feedback circuit.

摘要： A bus station in the form of a hardware dongle, operates in conjunction with a USB Device running suitable software. When the bus station determines that a bus host is connected to a first bus communication port thereof, it acts as a transceiver to allow conventional bus communications between said bus host and a bus device connected to a second bus communication port thereof. When the bus station determines that a bus device running suitable software is connected to the first bus communication port thereof, it acts as an alternate host to allow bus communications between said bus device connected to the first bus communication port and a bus device connected to a second bus communication port.

摘要： The invention relates to a bus system comprising a first station and a second station coupled by a bus for transferring signals. The bus is arranged to operate according to a protocol in which said first station repeatedly sends requests for data to the second station. The protocol comprises a first mode for transferring the requests in a first request format at a first communication speed and at least a second mode for transferring said requests in a second request format at a second speed. The second station is arranged to receive requests in a mode selected from a group of modes comprising said first and second modes, and is arranged to give a first indication to said first station if it is arranged to operate according to the first mode and a second indication if it is arranged to operate according to the second mode. The first station comprises a processor, a controller, and a translator. The processor is operable to generate request properties for requests in the first request format. The controller is operable to generate the requests in the first request format from the request properties. The controller is also operable to transmit the request in the first format to the second station upon detection of the first indication and to forward the requests to the translator upon detection of the second indication. The translator is also operable to transmit the requests in the second format to the second station.

摘要： A bus connection device, in the form of a hardware dongle, can be connected to a first electronic device, in the form of a USB peripheral device, and a second electronic device can be connected thereto. The dongle can determine whether the second connected device is a USB host device or a USB peripheral device and, if the second electronic device is a USB host device, it is connected directly to the first electronic device. If the second electronic device is a USB peripheral device, the bus connection device operates to allow the first electronic device to operate as a host device. When the bus connection device is operating to allow the first electronic device to act as a USB host device, it regularly sends tokens to the first electronic device and to the second electronic device, to which the first electronic device can respond by transmitting data intended for the second electronic device, and to which the second electronic device can respond by transmitting data intended for the first electronic device.
