Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected configuration information. A settings registry is generated based on the user's selections. The settings registry and the user selected configuration information is utilized to generate the content, such as code, data, parameters, settings, etc. When the content is provided to the programmable computing device, the content initializes, configures, or controls one or more software and hardware aspects of the programmable computing device, such as boot sequence configurations, internal peripheral configurations, states of the programmable computing device, transitions between states of the programmable computing device, etc., and various combinations thereof.

Abstract: In an embodiment a device includes a first circuit and a second circuit, wherein the first circuit is configured to generate a fourth signal and a fifth signal by applying the phase shift respectively to a first signal and to a second signal and deliver a sixth signal corresponding to a sampling over one bit of the fourth signal, a seventh signal corresponding to a sampling over one bit of the fifth signal, an eighth signal corresponding to a sampling over one bit of a difference between the fourth and fifth signals, and a ninth signal corresponding to a sampling over one bit of a sum between the fourth and fifth signals, wherein the second circuit is configured to receive the sixth, seventh, eighth, and ninth signals and determine, during a first phase where the first and second signals are representative of a first known symbol of a QPSK constellation, a state of a first bit from among a first state and a second state based on the eighth and ninth signals.

Abstract: A method for controlling a signal envelope shape of modulation pulses in a driver of a wireless transmitter includes supplying a first voltage to the driver during a non-modulated state, supplying a second voltage configurable by a configurable modulation index value to the driver during a modulated state, switching between the non-modulated state and the modulated state comprising setting the modulation index value to configure the second voltage level at the same level as the first voltage and then switching between supplying the first voltage to the driver and supplying the second voltage to the driver, and filtering to a limited bandwidth the variations of the second voltage resulting from configuring the modulation index value.

Abstract: An optical filter includes a carrier layer made of a first material. A periodic grating of posts is disposed on the carrier layer in a periodic pattern configured by characteristic dimensions. The posts are made of a second material. A layer made of a third material encompasses the periodic grating of posts and covers the carrier layer. The third material has a refractive index that is different from a refractive index of the second material. Characteristic dimensions of the periodic grating of posts are smaller than an interfering wavelength and are configured to selectively reflect light at the interfering wavelength on the periodic grating of posts.
