摘要： A wireless hub, connected to the USB bus of a computer, and a wireless port, connected to a USB interface of a peripheral device, are provided, and wireless communication is performed between the two. The wireless hub performs communication with the computer by converting a USB packet routed to a device into a wireless signal, and a wireless signal received from a device into a USB packet. The wireless port attached to each device also converts a wireless signal into a USB packet and vice versa. While it is normal for a plurality of wireless ports to be connected to a single wireless hub, an arrangement of one wireless hub and a corresponding single wireless port is also possible. A wireless hub and a wireless port each have a device identifier assigned to them, and in the USB-wireless conversion, a non-specific destination identified by a USB address and bus topology is converted into a device identifier. Inter-host communication is enabled by using the device identifier.

摘要： A reconfigurable processing system executes instructions and configurations in parallel. Initially, a first instruction loads configurations into configuration registers. The configuration field of a subsequently fetched instruction selects a configuration register. The instruction controls and controls of the configuration in the selected configuration register are decoded and modified as specified by the instruction. The controls provide data operands to the execution units which process the operands and generate results. Scalar data, vector data, or a combination of scalar and vector data can be processed. The processing is controlled by instructions executed in parallel with configurations invoked by configuration fields within the instructions. Vectors are processed using a vector register file which stores vectors. A vector address unit identifies addresses of vector elements in the vector register file to be processed. For each vector, vector address units provide addresses which stride through each element of each vector.
