摘要： A byte synchronization detection system and method in which a vector subtractor circuit determines an error vector between a current read data pattern and a synchronization bit pattern, and an offset adder circuit determines a Hamming Distance of the next read data pattern by adding the difference between the Hamming Distance from current error vector to the synchronization bit pattern and the Hamming Distance from the next error vector to the synchronization bit pattern. The Hamming Distance is determined by selected elements of the error vector which are the output from the vector subtractor circuit. The offset adder circuit determines a difference between the Hamming Distance of the current read data pattern and of the next read data pattern. The synchronization bit pattern is between 16 and 18 bits in length, inclusive. This approach reduces the probability of synchronization failure and/or mis-synchronization about 4 orders of magnitude over conventional approaches, while also reducing the length of the byte synchronization pattern to 16 bits.

摘要： A duty cycle tuner measures high and low periods of a signal, calculates an actual duty cycle, generates duty control signals based on the actual duty cycle and a desired duty cycle, and adjusts the duty cycle responsive to the duty control signals. The high and low periods are measured using high-speed counters to provide a high count for the high period and a low count for the low period. The actual duty cycle value is then computed from the high and low counts, and compared to the desired duty cycle value to generate increment and decrement signals which may be positive or zero, to increase, decrease or maintain the actual duty cycle. In this manner, even if the high and low counts are subject to variations due to process, temperature or power supply voltage, their ratio is independent of such variations, so the tuner is immune to those effects.

摘要： A barrel shifter uses a sign magnitude to 2's complement converter to generate decoder signals for its cascaded multiplexer selectors. The sign input receives the shift direction and the magnitude input receives the shift amount. The sign magnitude to 2's complement converter computes an output result as a 2's complement of the shift amount using the shift direction as a sign input, assigns a first portion (most significant bit half) of the output result to a first decoder signal, and assigns a second portion (least significant bit half) of the output result to a second decoder signal. This encoding scheme allows the decoder circuits to be relatively simple, for example, 3-to-8 decoders for an implementation adapted to shift a 64-bit operand value rather than the 4-to-9 decoder required in a conventional barrel shifter, leading to faster operation, less area, and reduced power consumption.

摘要： A low power oscillator circuit for a self-refresh timer in a memory array is disclosed. When a voltage (V1) of a comparison node (N1) exceeds a first reference voltage (Vref1), a differential amplifier (101) in an oscillator (1) causes a pulse generator (110) to output a pulse. A charge/discharge circuit (105) discharges the comparison node (N1) in response to pulse. In this event, a control circuit (4) disables a first control signal (CT1) to halt operation of the differential amplifier (101). When the voltage (V1) exceeds a second reference voltage (Vref2) equivalent to the sum of threshold voltages of a discharge circuit (43) in consequence of gradually charging the comparison node (N1) by the charge/discharge circuit (105) after it was discharged, the control circuit (4) activates the first control signal (CT1) to operate the differential amplifier (101).
