摘要:
A timing circuit independently controls placement of the positive and negative edges of a periodic signal. This signal may then be used to control a wide variety of integrated circuit applications. The timing circuit includes separate programmable delay lines and a signal processor. Each delay line delays an input clock signal by a different increment of time. The signal processor then generates a timing signal from the clock signal, where the timing signal has a first edge controlled by the first delayed clock signal and a second edge controlled by the second delayed clock signal. The edges may be controlled so that the timing signal assumes different logical values for different amounts of time, thereby customizing the signal to any application. An example of one application includes using the timing signal control switching in a DC-DC converter.

Methods and apparatus to reduce minimum operating voltage through a hybrid cache design are described. In one embodiment, a cache with different size bit cells may be used, e.g., to reduce minimum operating voltage of an integrated circuit device that includes the cache and possibly other logic (such as a processor). Other embodiments are also described.

Methods and apparatus relating to disabling one or more cache portions during low voltage operations are described. In some embodiments, one or more extra bits may be used for a portion of a cache that indicate whether the portion of the cache is capable at operating at or below Vccmin levels. Other embodiments are also described and claimed.

An error-detection flip-flop is disclosed for identifying timing errors in digital circuits. The error-detection flip-flop is a master-slave flip-flop including logic to determine whether an input signal is received during a predetermined clock period, signifying a timing error. The error-detection flip-flop produces a variable-length error pulse, which may be combined with other error pulses and converted to a stable signal for sampling by error-correction circuitry. The error-detection flip-flop does not increase the clocking power of the digital circuit and consumes little additional circuit area.

For one disclosed embodiment, an apparatus may comprise cache memory circuitry including multiple portions of destructive read memory cells and access control circuitry to access portions of destructive read memory cells. The apparatus may also comprise address hash logic to receive an address and to generate a hashed address based at least in part on at least a portion of the received address using a hashing technique to help distribute accesses by the access control circuitry across different portions of destructive read memory cells. Other embodiments are also disclosed.

Systems and methods are disclosed for measuring signals on an integrated circuit die. In one embodiment, a reference signal is distributed to die locations proximal to the signals to be measured. The reference signal is transmitted over transport paths coupling each of the signals to be measured to the die output. The signals to be measured are transmitted over their respective transport paths and measured at the die output. The relative delay between the signals can be calculated using the reference signal measurements.

In some embodiments, a circuit is provided that comprises a dynamic circuit and a body bias circuit. The dynamic circuit has a keeper transistor. The body bias circuit is coupled to the keeper transistor and is configured to body bias the keeper transistor in accordance with a leakage associated with the dynamic circuit. Other embodiments are disclosed herein.

A method is described that comprises flowing current from one region of a coil to another region of the coil. The flowing induces—through flux linkage—a voltage across a second coil. A second current substantially does not flow through the second coil. The method also includes measuring the current with a first voltage at the another region of the coil and a second voltage at the second coil.

DC/DC converters using dynamically adjusted variable size switches are described herein. In one embodiment, a power switch includes multiple switching elements coupled to each other, each of the switching elements independently switching to convert an input voltage to an output voltage of a DC/DC converter, and a duty cycle of the DC/DC converter being determined based on a duty cycle of each of the switching elements. Other methods and apparatuses are also described.
