摘要： In a digital PLL circuit outputting a clock signal with a frequency obtained by multiplying a frequency of a reference signal by a frequency command word (a frequency ratio), an RPA serially adds a frequency command word containing a fractional component. An output of the RPA is input to a minute phase error generator. The phase error generator generates a plurality of threshold values close to an actual amplitude value of the reference signal based on the fractional portion of the serially added value of the frequency command word, calculates the amplitude value of the reference signal and a phase error of the reference signal corresponding to the amplitude value based on the threshold values, and calculates a minute phase error between the reference signal and the output clock.

摘要： An analog complex filter combines an in-phase signal and a quadrature signal to output first and second analog signals. An analog-to-digital converter converts the first and second analog signals into first and second digital signals. A digital complex filter attenuates components corresponding to the quadrature signal and the in-phase signal of the first and second digital signals, respectively. A digital bandwidth limited filter allows a target component and an image component contained in the digital complex signal composed of the first and second digital signals from the digital complex filter to pass therethrough, and attenuates an adjacent interference component. An IQ imbalance correction circuit corrects a quadrature error and an amplitude error between the first and second digital signals from the digital band-pass filter.

摘要： In arithmetic/logic units (ALU) provided corresponding to entries, an MIMD instruction decoder generating a group of control signals in accordance with a Multiple Instruction-Multiple Data (MIMD) instruction and an MIMD register storing data designating the MIMD instruction are provided, and an inter-ALU communication circuit is provided. The amount and direction of movement of the inter-ALU communication circuit are set by data bits stored in a movement data register. It is possible to execute data movement and arithmetic/logic operation with the amount of movement and operation instruction set individually for each ALU unit. Therefore, in a Single Instruction-Multiple Data type processing device, Multiple Instruction-Multiple Data operation can be executed at high speed in a flexible manner.

摘要： In a digital PLL circuit, a phase comparison circuit counts the numbers of transitions of a reference clock and an oscillation clock, sets a time taken until the number of transitions of the reference clock reaches a reference count value as a phase comparison time period, and detects, as a phase error value, a difference between a target count value, obtained based on a magnification value of a desired oscillating frequency with respect to the frequency of the reference clock and the reference count value, and the number of transitions of the oscillation clock in the phase comparison time period. A smoothing circuit smoothes the phase error value. A digitally-controlled oscillation circuit controls the frequency of the oscillation clock in accordance with the phase error value smoothed by the smoothing circuit.
