摘要： A PLD (200) includes a power management unit (PMU 210) that selectively implements one or more different power-reduction techniques in response to power configuration signals (PC). By manipulating the PC signals, the PMU can independently enable/disable various supply voltage circuits (110, 120, 130) that power CLBs (101), IOBs (102), and configuration memory cells (106), can generate a capture signal that causes data stored in storage elements of the CLBs to be captured in configuration memory cells, and/or can switch power terminals of configuration memory cells between voltage supply circuits. Also, the PMU can sequentially apply and remove power from a number of configurable PLD portions in response to the PC signals, wherein each configurable portion may include any number of the PLD's resources.

摘要： An apparatus is disclosed that may reduce the dynamic power dissipation of a configurable IC device such as an FPGA by reducing the peak-to-peak voltage swing of signals transmitted over the device's interconnect signal lines without including additional level shifter circuits. For some embodiments, existing multiplexing circuit architectures provided within logic resources of various logic blocks of the configurable IC device may be used as level shifter circuits to increase the voltage swing of signals received into the blocks from the interconnect signal lines, and modified multiplexing circuit architectures provided within the logic resources may be used to reduce the voltage swing of signals output from the logic blocks onto the interconnect signal lines.

摘要： A PLD utilizes a heterogeneous architecture to reduce power consumption of its active resources. The PLD's programmable resources are divided into a first partition and a second partition, where the resources of the first partition are optimized for low power consumption and the resources of the second partition are optimized for high performance. Portions of a user design containing non-critical timing paths are mapped to and implemented by the resources of the power-optimized first partition, and portions of the user design containing critical timing paths are mapped to and implemented by the resources of the performance-optimized second partition.

摘要： Leakage current reduction from a logic block is implemented via power gating transistors that exhibit increased gate oxide thickness as compared to the thin-oxide devices of the power gated logic block. Increased gate oxide further allows increased gate to source voltage differences to exist on the power gating devices, which enhances performance and reduces gate leakage even further. Placement of the power gating transistors in proximity to other increased gate oxide devices minimizes area penalties caused by physical design constraints of the semiconductor die.

摘要： Power-gating circuit resources of an integrated circuit is described. The circuit resources are associated into sets responsive to utilization levels. The associating includes providing a first set of the sets, a first number of the circuit resources in the first set being associated with a first level of utilization. The associating also includes providing a second set of the sets, a second number of the circuit resources in the second set being associated with a second level of utilization. The first number is less than the second number responsive to the first level of utilization being greater than the second level of utilization. The circuit resources of the first set are commonly coupled to a reference voltage level via a first gating circuit. The circuit resources of the second set are commonly gated to the same or a different reference voltage level via a second gating circuit.

摘要： A configurable latch is implemented using a configurable pulse generator and a level sensitive (LS) latch. The configurable pulse generator produces either a pulse signal that is aligned with the input clock edge, or simply provides the input clock signal to its output in response to a pulse generator control signal. If a pulse signal is provided to the latch, then edge triggered (ET) latch operation is effected within the latch. If, on the other hand, a clock signal is provided to the latch, then LS latch operation is effected within the latch. Thus, configuration of latch operation is established in response to the type of clock signal that is provided to the latch.

摘要： An apparatus and method for the dynamic detection and compensation of performance variations within an integrated circuit (IC) is provided to detect performance variations within the IC at any stage of test or operation. An arbitrary reference signal is utilized in conjunction with an internal oscillation device to establish a speed reference that may be used to characterize the IC. Dynamic detection and compensation may also be configured within a plurality of geographic locations within the IC, so that performance variations may be detected and compensated. Test data that is indicative of the IC's performance may be dynamically generated continuously, or at programmable intervals, so that performance variations caused by virtually any source may be substantially detected and compensated at any point in time of the IC's life cycle.
