A scheme is described for distributing data operations on an irregular data stream over multiple stages of a data aligner to generate a regular data stream having continuous filled byte positions. In one particular embodiment, the number of unaligned data scenarios may be reduced through the use of data stream element mapping. A complex data stream may be mapped onto a simple data stream with only the addition of multiplexers and simple logic to the data aligner. The implementation in network protocol related hardware, where a data stream is encoded and decoded for error detection and correction, may lead to a faster and more efficient pipelined design of checkers and generators, thereby, making them more desirable for higher frequency and higher bandwidth designs.

A scheme is described for distributing data operations on an irregular data stream over multiple stages of a data aligner to generate a regular data stream having continuous filled byte positions. In one particular embodiment, data alignment may involve the prediction of a rotation amount for unaligned data bytes. The rotation amount is predicted one clock cycle before actual rotation of data bytes based on the current contents of a buffer. The one cycle look ahead enables a large portion of calculations to be performed in a previous clock cycle and, thereby, may facilitate a high frequency design for a data aligner.

A data communications device that can operate in accordance with two or more protocols having different data formats and error-protection schemes. The protocol-dependent aspects of the device are handled by a peripheral portion of the device, allowing a substantially protocol-independent core portion that is insulated from protocol changes. Translation and/or adaptation mechanisms in the peripheral portion of the device allow the device to handle changes in data format and/or pipeline changes such as error protection without affecting the core portion of the device. A device and method are provided for inter-operating with both the Spatial Reuse Protocol (SRP) and the Resilient Packet Ring (RPR) architectures.

A frame delineation mechanism which alternately considers even and odd sync pattern position possibilities. With the addition of toggle logic, each of 66 possible states of even and odd alignment are exhausted in turn, odd, followed by even, followed by odd and so on, providing synchronization more quickly than known mechanisms. Additionally, faster convergence is reached due to the use of an exhaust register which keeps track of those alignment states that were tested but did not provide synchronization. Until synchronization is acquired, the states indicated in the exhaust register are ignored in further attempts to acquire synchronization.

An encapsulation packet is received as a sequence of parallel data segments. First information within the encapsulated packet is obtained based on second information indicative of a location of the first information within the encapsulated packet. The encapsulating header is modified based on the first information.

In processing received virtual concatenation frames, the memory write address can be appropriately controlled to force bank switches where address scattering occurs. Arbitrary identifiers assigned to the arriving frames and the subcolumns thereof are used instead of H4 information to calculate the memory write addresses.

A system and method is disclosed for measuring thickness of at least one film on a substrate by propagating an acoustic wave through the film on a substrate such that echo waves are generated and received by a transducer. An output signal is generated and processed to give a thickness value. The thickness valve is obtained from the time lapse between the propagated wave and receipt of the echo wave; by the frequency domain of the echo wave; or the phase of the echo wave.

An integrated device for connected cars that provides a plurality of standard and new interfaces, which is implemented in flexible hardware to overcome the mismatch between an automobile lifetime and cellular and semiconductor technology development. By providing interfaces in one device, greater synergy of applications is possible. Integration of the on board diagnostics with the infotainment device is a function enabler for the automobile ecosystem. The present invention is open to integration with the car electronic driver assistance and evolving autonomous driver modules, providing additional economies of scale.
