Abstract: An embedded field programmable gate array (EFPGA) includes several abuttable configurable logic blocks (ACLBs). Each ACLB is interconnected with adjacent ACLBs by abutment of an out pin to an adjacent in pin. Each ACLB may be an instance of multiple programmable functional blocks. Each ACLB may be a particular ACLB type that provides a particular instance of the multiple programmable functional blocks. The EFPGA may include several ACLBs of the same type. An ACLB of one type may be adjacent an ACLB of a different type. The ACLBs may form sets that are configured identically. The sets may be interconnected by abutment of an out pin to an adjacent in pin. The EFPGA may be part of a system-on-chip integrated circuit. A method for designing an EFPGA with ACLBs that are interconnected by abutment is disclosed.

Abstract: A method for determining an absolute angular position of a crankshaft target of an internal combustion engine, including a plurality of teeth for which at least one signal is acquired representing the passage of each tooth in front of a sensor as a function of time comprising: i. generating during a phase with the engine running an absolute angular position from the at least one signal and from a period of a tooth; ii. continuously determining during a phase of stopping the engine when determination of the period is not possible, a number of teeth passing in front of the sensor; and iii. during a phase of restarting the engine, using a number of teeth to reduce the cycle synchronization time.
Abstract: An input/output (IO) pad circuitry for integrated circuits (ICs) that is equipped with safety monitoring and control circuits to ensure that signals provided to/from the IO pad behave correctly. The IO pad circuitry allows monitoring of the IO pad signals, the detection of an undesired behavior, e.g., a wrong signal level or a wrong waveform. Furthermore, depending on a selected safety mode, a correction of the IO pad signals by overriding the monitored signal is further achieved. When in full safe mode, signals are provided as required, while in a partial safe mode only certain signals are provided depending on the status. A grouped safe mode allows providing a safe status to a group of IO pads using a single control. A monitoring circuitry between a plurality of input signals to an IC pad is also provided.
Abstract: Field programmable gate arrays (FPGA) contain, in addition to random logic, also other components, such as processing units, multiply-accumulate (MAC) units, analog circuits, and other elements, configurable with respect of the random logic, to enhance the capabilities of the FPGA. A circuit for a filed configurable MAC unit is provided to allow various configurations of ADD, SUBTRACT, MULTIPLY and SHIFT functions. Optionally, registered input and registered output support a multi-cycle path. A configuration of a constant facilitates the configuration of the circuit to perform infinite impulse response (IIR) and finite impulse response (FIR) functions in hardware.
