摘要： A testing system includes a tester probe and a plurality of integrated circuits. Tests are broadcast to the plurality of integrated circuits using carrierless ultra wideband (UWB) radio frequency (RF). All of the plurality of integrated circuits receive, at the same time, test input signals by way of carrierless UWB RF and all of the plurality of integrated circuits run tests and provide results based on the test input signals. Thus, the plurality of integrated circuits are tested simultaneously which significantly reduces test time. Also the tests are not inhibited by physical contact with the integrated circuits.

摘要： A system has a first plurality of cores in a first coherency group. Each core transfers data in packets. The cores are directly coupled serially to form a serial path. The data packets are transferred along the serial path. The serial path is coupled at one end to a packet switch. The packet switch is coupled to a memory. The first plurality of cores and the packet switch are on an integrated circuit. The memory may or may not be on the integrated circuit. In another aspect a second plurality of cores in a second coherency group is coupled to the packet switch. The cores of the first and second pluralities may be reconfigured to form or become part of coherency groups different from the first and second coherency groups.

摘要： An integrated circuit has a group of cores that communicate with a packet switch using carrierless ultra wideband (UWB) radio frequency (RF) signaling. The packet switch communicates outside the integrated circuit using optical signaling. The carrierless UWB provides for high frequency communication and processing without requiring additional space for interconnects. No special paths are necessary because the signals used by the cores for communicating with the packet switch are RF signals therefore they can be broadcast by the packet switch and be received by a plurality of cores. No conductor line or waveguide is required. Because the signals are carrierless, they can be transmitted with low power. With multiple cores providing information to the switch, the total information being received may exceed the capacity of the RF bandwidth so an external optical interface is provided to multiplex information provided via carrierless UWB RF signals by a plurality of cores.

摘要： A memory device (201) includes a plurality of memory cells (203), bit lines, word lines, a sense amplifier (314), and a self-timed latch (215). The sense amplifier (314), responsive to a sense enable signal, is for sensing and amplifying a voltage on the bit lines corresponding to a stored logic state of a selected one of the plurality of memory cells. An isolation circuit (306, 308) is coupled between the bit lines (205 and 207) and the sense amplifier (314). The isolation circuit (306, 308) is for decoupling the selected one of the plurality of memory cells from the sense amplifier (314) at about the same time that the sense enable signal is asserted. A self-timed latch (215) is coupled to the sense amplifier (314). The self-timed latch (215) does not receive a clock signal and is responsive to only the amplified voltage.
