Abstract: Systems and methods for phase detection are disclosed. A collapsible three-stage pipeline includes a first register in a first stage having a first clock signal having first clock edges, a second register in a second stage that receives a first signal from the first stage, and having a second clock signal having second clock edges, and a third register in a third stage that receives a second signal from the second stage, and having a third clock signal having third clock edges, wherein each second clock edge has a corresponding first clock edge and a corresponding third clock edge. The circuitry may further include a two-stage pipeline including fourth and fifth stages, a counter that provides an input signal into the collapsible three-stage pipeline and the two-stage pipeline, and a comparator that compares a first output of the collapsible three-stage pipeline and a second output of the two-stage pipeline.

Abstract: Enhanced memory circuits are described that maintain coherency between concurrent memory reads and writes in a pipelined memory architecture. The described memory circuits can maintain data coherency regardless of the amount of pipelining applied to the memory inputs and/or outputs. Moreover, these memory circuits may be implemented as dedicated hard circuits in a field programmable gate array (FPGA) or other programmable logic device (PLD), and can be supplemented with user-configurable logic to achieve coherency in a variety of applications.

Abstract: An integrated circuit may have circuitry that includes a storage circuit, a processing circuit, and at least one state register to implement a finite-state machine. The storage circuit may store base addresses and output data for each state of the finite-state machine. The storage circuit may further store offset values that are based on the input data to the finite-state machine and the state transition from a current state to a next state caused by the input data. The processing circuit may compute the address of the storage circuit location where the output data of the next state is stored. The computation of this address may depend on the offset value and base address of the current state. The state register may receive the address from the processing circuit, store the address, and perform the corresponding memory access operation on the storage circuit.

Abstract: Embodiments of crossbar devices constructed with Micro-Electro-Mechanical Systems (MEMS) switches are disclosed herein. A crossbar device may comprise m input terminals, n output terminals, n control lines and m×n MEMS switches coupled to the n control lines to selectively couple the m input terminals to the n output terminal. Each of the MEMS switches may comprise a contact node coupled to one of the m input terminals, a cantilever coupled to one of the n output terminals, a control node coupled to one of the n control lines to electrostatically control the cantilever to contact the contact node or be away from the contact node using electrostatic attractive or repulsive force respectively. The cantilever and the contact node are configured to remain in contact by molecular adhesion force, after the cantilever has been electrostatically controlled to contact the contact node, and the electrostatic attractive force has been removed. Other embodiments may be described and claimed.

Abstract: The method, system and tangible medium storing computer readable software of the present invention, provide for program constructs, such as commands, declarations, variables, and statements, which have been developed to describe computations for an adaptive computing architecture, rather than provide instructions to a sequential microprocessor or DSP architecture.

Abstract: Disclosed is a microwave cooking package and tray suitable for cooking food. The package and tray comprise a laminate structure comprising a lid, susceptor layer upon a backing material, and a plurality of apertures through said laminate structure. This permits uniform cooking and browning of dough enrobed food items and venting of excess moisture to help to control heat generation under the food being cooked, as the apertures remove a portion of the susceptor material.

Abstract: A pedometer is disclosed that accurately calculates the length of the strides taken by a user when walking and running. The length of each stride is calculated using measurements of the acceleration of the wearer's foot during each stride. This acceleration is measured by an accelerometer attached either directly or indirectly to the wearer's foot. The calculation of the stride length is performed by a data processor which analyzes the accelerations of the foot as measured by the accelerometer. The acceleration values for each stride are identified, and these are used in conjunction with a set of coefficients to calculate the length of each stride. These coefficients are determined for each user by means of a calibration process during which the pedometer measures the characteristics of the wearer's stride for a variety of different walking and running speeds.

Abstract: A configurable computing architecture (10) has its functionality controlled by a combination of static and dynamic control, wherein the configuration is referred to as static control and instructions are referred to as dynamic control. A reconfigurable data path (12) has a plurality of elements including functional units (32, 36), registers (30), and memories (34) whose interconnection and functionality is determined by a combination of static and dynamic control. These elements are connected together, using the static configuration, into a pipelined data path that performs a computation of interest. The dynamic control signals (21) are suitably used to change the operation of a functional unit and the routing of signals between functional units. The static control signals (23) are provided each by a static memory cell (62) that is written by a host (13). The controller (14) generates control instructions (16) that are interpreted by a control path (18) that computes the dynamic control signals.
