摘要： A design structure for an integrated circuit that includes input/output (I/O) state saving circuitry capable of stabilizing the I/O states during any predicted I/O disturbance event. The I/O state saving circuitry includes a plurality of transparent latches arranged between the output of a plurality of respective I/O receivers and the internal digital, analog, or mixed-signal circuitry of the integrated circuit. The transparent latches are transitioned between a pass-through mode and a state-saving mode via a common control signal. In anticipation of, for example, a predicted I/O signal disturbance generating event, the transparent latches are set to the state-saving mode. Consequently, the outputs of the transparent latches are held stable and glitchless during the disturbance event, which ensures that the internal logic of the integrated circuit does not lose state.

摘要： Disclosed are an object locator system, a method and a program storage device. In the embodiments, radio frequency identification (RFID) tags are on objects within a defined area and each RFID tag can be activated by an RF activation signal. When a request (e.g., a verbal or keyed-in request) to locate a specific object is received from a specific user, the required permission to locate the object is verified and, optionally, the identity of the specific user is authenticated. Once the required permission is verified and the identity of the specific user is authenticated, one of three RFID readers transmits an RF activation signal. RF response signals received back at the three RFID readers from the specific object's RFID tag are used to triangulate the position of the specific object. Once determined, the position is communicated (e.g., by map display, verbal message, or text message) to the specific user.

摘要： Fuse macros of identical number of pages are serially arranged to form the same number of fusebay pages each having a length equal to the sum of the respective fuse macro page lengths. Each fuse macro has an enable latch configured to allow activation of one fuse macro at a time. A fusebay control device connected to a repair register may store data in and retrieve data from the fusebay. Next available fuse location is determined in programming mode so that data from a next repair pass may start where the last data ended.

摘要： The invention provides a circuit that can observe data within shift registers without altering the data. The circuit includes selectors connected to the inputs and outputs of the shift registers. The selectors selectively connect the input with the output of a selected shift register to form a wiring loop for the selected shift register. A control device connected to the wiring loop uses the wiring loop to cause the data to be continually transferred from the output of the selected shift register to the input of the selected shift register and back through the selected shift register in a circular manner. The control device includes a counter used for determining the length of a selected shift register and a set of registers to store, for future use when rotating data in the shift registers, the length of each shift register. The control device also includes a data output accessible from outside the circuit. An observation wire is connected to the wiring loop, and the data passes from the wiring loop to the control device through the observation wire. The control device outputs data appearing on the wiring loop as the data is circulated through the selected shift register to permit data within the selected shift register to be observed outside the circuit without altering the data within the selected shift register.

摘要： Multi-state restore circuitry that allows storage elements of a power-managed functional block to be loaded when the functional block is repowered up so that the functional block is ready for operation virtually immediately after voltage ramp-up of the functional block. The multi-state restore circuitry includes a restore-state detector for determining which one of a plurality of restore states of the functional block is applicable to a particular repowering-up of the functional block. The multi-state restore circuitry also includes restore logic that loads the storage elements as a function of the restore state determined by the restore-state detector.

摘要： A structural design-for-test for diagnosing broken scan chain defects of long non-scannable register chains (GPTR) The GPTR and the system for testing and diagnosing the broken LSSD scan-only chains rapidly localize defects to the failing Shift Register Latch (SRL) pair. The GPTR modifies the latches used in the GPTR scan chain to standard LSSD L1/L2 master-slave SRL type latch pairs; connects all the system ports of the L1 latches to the Shift Register Input (SRI) and clocked by the system C1-clk while the L1 scan port is clocked by the A-clk and L2 scan port is clocked only by the B-clk. The L1 latches are connected to at least one multiplexer having a first output connected to an input of each odd SRL, and a second output connected to an input port of each even SRL. In another embodiment, the GPTR includes a plurality of multiplexers respectively coupled to the master-slave latch pairs, wherein a first set of multiplexers have their respective output attached to an input of the odd L1 latches, and a second set of the multiplexers have their respective output attached to an input port of the even L1 latches.
