An area efficient readable and resettable configuration memory latch maintains latch data integrity through read and write operations and includes a non-terminated inout bit line (BL). During write operations, enabled by a Word Line Write (WLW) signal, the non-terminated inout BL drives data to be written, while, during read operations, enabled by a Word Line Read (WLR) signal, the state of the BL is indicative of a data stored in the latch. A pull-down network is activated when the WLR signal is asserted and the stored data is logic one and, when activated, operates to pull down the BL to logic zero; the pull-down network is inactive otherwise. A weak pull-up operates to pull up the BL when the pull-down network is inactive. A sensing block is configured to sense the state of the BL when the WLR signal and a read enable signal are both asserted.

A sensor hub includes a bit packer that receives sensor data from a plurality of sensors and bit packs the sensor data so that the sensor ID, time stamp and each axis of the measured data is stored contiguously. The bit packer may compress the sensor data by removing the sensor ID and/or the time stamp in the sensor data. The bit packed sensor data is stored in batching memory. A bit unpacker receives the sensor data from the batching memory and unpacks the sensor data, e.g., so that the sensor ID, time stamp and each axis of the measured data is stored in its own word. Additionally, the bit unpacker may decompress the bit packed sensor data by reinserting the sensor ID and/or time stamp in the sensor data.

End-user software is used to select lists of values of control signals from a predetermined design of a processor, and a unique value of an opcode is assigned to each selected list of values of control signals. The assignments, of opcode values to lists of values of control signals, are used to create a new processor design customized for the end-user software, followed by synthesis, place and route, and netlist generation based on the new processor design, followed by configuring an FPGA based on the netlist, followed by execution of the end-user software in customized processor implemented by the FPGA. Different end-user software may be used as input to generate different assignments, of opcode values to lists of control signal values, followed by generation of different netlists. The different netlists may be used at different times, to reconfigure the same FPGA, to execute different end-user software optimally at different times.
A routing network is associated with a logic island in a logic block of a programmable logic device and includes switches for each of feedback, street, and highway networks. Some of the switches include multiple stages. The street network switch receives the signals from the feedback network switch, signals from neighboring highway network switches, and direct feedback from selected logic island outputs and provides outputs to the logic island. The street network switch includes multiple stages, where outputs to the logic island are provided directly by each stage in the street network switch. The output terminals of a first stage of the street network switch that are connected to the logic island are also connected to the second stage of the street network switch. The second stage of the street network switch receives feedback output signals from the feedback network and directly from the associated logic island.

A wrist worn heart rate monitor includes a photoplethysmogram (PPG) sensor and an inertial sensor. Signals from the inertial sensor are used to identify and remove noise from the PPG signals. An initial heart rate value is selected from a number of heart rate candidates that remain in the resulting PPG spectrum and is used to track the heart rate of the user. The PPG spectrum is monitored while tracking the heart rate to determine if the selected initial heart rate value is in error. The PPG spectrum may be monitored by determining a correlation of possible heart rate candidates in each PPG spectrum to the previous heart rate candidates and resetting the heart rate value accordingly. Additionally or alternatively, the PPG spectrum may be monitored by determining when only a single heart rate candidate is present in consecutive PPG spectra and resetting the heart rate value accordingly.
A wrist worn pedometer includes a multiple axis inertial sensor. Signals from each axis of the multiple axis inertial sensor are received and are separately analyzed to determine which axis is producing a stable periodic signal, which is selected as the counting axis, i.e., the axis to be used for counting steps. Additionally, the pedometer determines whether the counting axis is registering arm movement or footsteps. The user's steps are counted based on the detected events, e.g., detected peaks or intervals between peaks, on the signal from the counting axis. One step per detected event is counted if the counting axis is registering footsteps and two steps per detected event are counted if the counting axis is registering arm movement. If the stability of the selected counting axis is lost, another axis is selected as the counting axis if it is producing a stable periodic signal.

A logic cell in a programmable logic device receives an external signal from a routing network that serves as a select signal that selects a combinatorial logic signal via a first multiplexor as well as a data input to a second multiplexor. The second multiplexor selects between the combinatorial logic signal and the external signal and provides an output signal to a register. Accordingly, the logic cell has the flexibility to support a combinatorial and/or sequential function using minimal routing resources. A third multiplexor may select the output from the register or another signal as the output signal from the logic cell. A clock signal to the register may be gated off when the register output is not selected as the output signal, thereby reducing dynamic power consumption. The programmable logic device may include a number of super logic cells, each of which includes a plurality of logic cells.

Embodiments of the present invention provide a unique capability of implementing a pair of pseudo-PHY interfaces using a bridge. From the host and device perspectives, the host and device communicate through a PHY interface. The bridge, however, avoids actually using a USB PHY interface. This PHY-less bridge allows communication between a host and a device at high speeds without high-power transceivers associated with a USB PHY interface. In accordance with the present invention, a host and a device may be coupled together using a PHY-less bridge using the same interface or translating between different interfaces by using a wrapper. Such PHY-less bridges include a UTMI-to-UTMI bridge, a UTMI-to-ULPI bridge, a ULPI-to-UTMI bridge and a ULPI-to-ULPI bridge, each avoiding the need for a USB PHY interface.
