Abstract: Assembly structures are characterized to allow electronic components quick, safe, easy to modify (manipulate by hands without tools), and visually intuitive (topographic) three-dimensional construction of circuits. The assembly structure allows an electronic component lead to connect to a neodymium iron boron magnet within the structure and extend the connection to other assembly structures having the same through a chrome steel ball magnetically attracting both assembly structures. The assembly structures house electronic components such as a resistor, capacitor, variable capacitor, inductor, diode, transistor, transformer, integrated circuit, wired battery clips, and a wired earpiece.

Abstract: An apparatus and method which provide increased data flow through a compute platform by optimizing data flow between an external device and the internal circuitry without the need for user intervention. A port router is provided which includes a controller switch, a port switch, and one or more connections between the controller switch and the port switch. The controller switch, the port switch and the one or more connections are adapted to provide dynamic re-routing of connections between the port switch inputs and the controller switch outputs. A method is also provided for dynamically routing ports to internal circuitry of a compute platform.

Abstract: An IO controller device and method for controlling data flow, the method including determining a desired configuration for the IO controller, reprogramming the IO controller to allow for processing of one or more descriptor lists, modifying the configuration of the IO controller to reflect the addition or deletion of one or more virtual controllers, re-enumerating the IO controller, and processing a descriptor list for each of the IO controller and the one or more virtual controllers. The integrated circuit device for use as an IO controller includes a system bus interface, a programmable list processor and a port router. The integrated circuit device is adapted for reconfiguration to add or delete one or more virtual controllers. The virtual controllers provide substantially the full bandwidth supported by the integrated circuit device.

Abstract: A digit reversing system is disclosed for handling mixed radix FFT operations with arbitrary arrangements of radices. In a first step, all bits in an integer field of size log.sub.2 N are position reversed. In a second step, subfields of the output produced in the first step are individually unreversed at the local level to produce unreversed digits. The output is used for appropriately arranging input terms applied to a mixed-radix multi-stage Fast Fourier Transform (FFT) process.

Abstract: A control apparatus for use with a digital signal processing device and associated memory units is described. The control apparatus determines, along with the electrical configuration of the digital signal processing device and associated memory units, the application of members of a signal array to be processed and the removal of the members of a processed signal array from the digital signal processing device. The control apparatus controls the location of data exchanged between the digital signal processing device and the associated memory units.
