摘要： A true random number generator (RNG) has one or more oscillators and an output register for storing a random number output. Each of the oscillators is activated, successively, in a free-running oscillation phase, and a capture phase during which the oscillator is quiescent. The output register latches during the capture phase of each oscillator an end state of that oscillator at or close to the end of its oscillation phase. The random number output is derived from the latched end states.

摘要： A hardware interface component arranged to operably couple at least one arithmetic unit to a an interconnect component of a processing system. The hardware interface component comprises a plurality of program-visible registers and at least one operation decoder component. The at least one operation decoder component is arranged to, upon receipt of a write access request via the interconnect component corresponding to a decorated memory-mapped address range for the hardware interface component, decode a register identifier component of a target address of the received write access request to identify at least one of the program-visible registers, decode a decoration component of the target address of the received write access request to identify an arithmetic operation to be performed, and configure the arithmetic unit to perform the identified arithmetic operation on at least one input operand within the identified at least one program-visible register.

摘要： A demodulator suitable for demodulating binary FSK signals having a small difference between carrier frequencies uses a counter-timer technique for timing a fixed number FSK cycles and comparing a count value with a threshold when a frequency change is expected. By grouping a number of FSK pulses (or cycles) together in one measurement, speed requirements on the system clock used for the counter/timer measurements can be relaxed and tolerance to noise is also improved. The demodulator is particularly suitable for wireless charging applications.
摘要翻译：适用于解调载波频率差小的二进制FSK信号的解调器使用计时器技术来定时固定数量的FSK周期，并且当预期频率变化时将计数值与阈值进行比较。通过在一次测量中将多个FSK脉冲（或周期）分组在一起，可以放宽用于计数器/定时器测量的系统时钟的速度要求，同时提高对噪声的容限。解调器特别适用于无线充电应用。

摘要： A touch sensor interface includes one or more touch detection electrodes whose capacitance increases when touched. A processor converts the increase in capacitance into a change in a counter value. A detector compares the change in the counter value with one or more count thresholds to detect faults in the touch sensor interface.

摘要： A sensor for sensing proximity or touch of an object includes a sensing region, an oscillating signal generator for generating an oscillating signal having an oscillation period, a gating signal generator for generating a gating signal having a gating duration, a controller for controlling the oscillation period or the gating duration and a processor for determining a number N of oscillation periods over the gating duration. The number N is indicative of the object's contact with, or proximity to, the sensing region. The sensor is calibrated by determining an optimal value for the oscillation period or gating duration such that an optimal number N over the gating duration is expected.
