Abstract: A computing device has a plurality of subsystems located in subsections that are moveable with respect to each other. Communication between the subsections is accomplished with wireless transceivers transmitting over the air gap interface separating the subsections. Data from multiple communicating subsystems in the subsections is multiplexed into a single data stream and encoded into the communication protocol of the wireless transceivers. The encoded data stream is transmitted to a compatible transceiver where it is decoded. The decoded data stream is demultiplexed into individual data streams for each of the communicating subsystems. The wireless transceivers include multiple communication protocols and transmission frequencies from radio frequencies to optical frequencies. Optical fibers, transmission lines or waveguides may be used to transmit signals within each subsection depending on the wireless technology and protocol.

Abstract: A data ALU (arithmetic logic unit) (54) in a data processing system (20) performs both 24-bit arithmetic, and 16-bit exact arithmetic (including shifting and logical operations) using the same hardware. For a multiply/accumulate operation in 16-bit exact mode, shifting operations are used to align the operands so that 16-bit exact mode is transparent to a user. An entire instruction set can be executed in 24-bit mode or 16-bit exact mode. The same instructions and hardware are used in both modes. A transition between modes is performed by changing a status bit (97) in a status register (95).
