Abstract: A crossbar device includes a first set of input lines and a second set of output lines. A plurality of chains of pass transistors are provided to selectively couple the input lines to the output lines in a reduced parasitic capacitive loading manner. Further, memory elements and decoder logic are provided to facilitate control of the selective coupling. Additionally, a low power application of multiple crossbar devices to a reconfigurable circuit block is improved by having each memory element of a crossbar device be provided with a supply voltage higher by a Vth to maintain the input voltage of corresponding output buffers at Vdd. Further, an application of multiple crossbar devices to a reconfigurable circuit block is improved by coupling a control circuitry via a control line to all output buffers of the interconnected crossbar devices to force the output buffers to a known state at power-on.
Abstract: An integrated circuit (IC) includes a number of function blocks (FB), of which at least one is re-configurable. Each of the FBs may be a reconfigurable function or a non-reconfigurable function or recursively expanded with additional “nested” function blocks. The IC further includes a number of input pins, a number of output pins, and a number of crossbar devices. The elements, at least at the IC level, are coupled in a manner such that all input signals are provided to the FBs through a first subset of the crossbar devices, all internal signals are routed from one FB to another FB through a second subset of crossbar devices, and all output signals are routed from the FBs to the output pins through a third subset of crossbar devices. To increase routability and speed each of the crossbar device output has a single fanout. Additionally, each of the crossbar devices may provide only one input to each other crossbar device.
Abstract: A trading card capable of generating sounds comprises a thin housing having front and back surfaces, flexible sheets affixed to the front surface and to the back surface of the housing, a voice chip located in the housing for generating patterns of sounds, a battery located in the housing for supplying electrical power to the voice chip, and a switch located in the housing for activating the voice chip. The subject trading card may be activated by squeezing the flexible sheets between the thumb and forefinger at a selected switch location.
