  • Patent number: 10673662
    Abstract: A method for generating M parallel pseudorandom binary sequences (PRBSs), each comprising a 2n?1 sequence of pseudorandom bits, includes loading into the circuit an initial M-bit word, the initial M-bit word comprising M sequential bits selected from a pre-determined PRBS-n sequence, wherein n>1 and M>n. The method includes generating, using a plurality of logic gates of the circuit, a next M-bit word using at least n+1 of the M sequential bits of the initial M-bit word. The method includes repeatedly generating, using the logic gates of the circuit, the next M-bit word from a previous M-bit word using the at least n+1 of M sequential bits of the previous M-bit word, resulting in M parallel sequences of the PRBS-n sequence. The method includes transmitting the generated next M-bit words on an M-bit wide parallel bus.

  • Patent number: 7366049
    Abstract: A dual port memory is updated at substantially the same data sampling rate as a clock frequency of the dual port memory. The dual port memory stores data relating to each different parameter value in a stream of data samples, and provides the stored data from an address in the memory corresponding to the received parameter value. An updating element updates stored data and provides the updated data to an input of the dual port memory for writing back into the address corresponding to the received parameter value. A first port of the dual port memory is utilised as the output of the dual port memory coupled to the input of the updating element on a first clock cycle of the dual port memory, and a second port of the dual port memory is normally utilised as the input of the dual port memory coupled to the output of the updating element on a second clock cycle, the next address being accessed via the first port on the second clock cycle.

  • Patent number: 7277820
    Abstract: In apparatus for generating a Complementary Cumulative Distribution Function (CCDF) curve for an input signal, an analog to digital converter (ADC) samples the input signal at sampling points to provide a parameter value corresponding to a desired parameter of the input signal at each sampled point. A memory element provides a frequency count of occurrence of each received parameter value from an address in the memory corresponding to the received parameter value. An adder receives the frequency count, increments the count and provides the incremented count to an input of the memory element for writing back into the address corresponding to the received parameter value. A CCDF curve generating module reads the frequency count stored in the memory element corresponding to each parameter value and generates a CCDF curve therefrom.

  • Patent number: 7265700
    Abstract: Digital samples corresponding to a pulsed input signal are provided from an ADC to a memory for storage and to a pulse extraction circuit. The pulse extraction circuit detects the leading and trailing edges of pulses in the input signal. The digital samples are stored in both a Current memory buffer and a Next memory buffer. When a pulse trailing edge is detected, the Current buffer is stopped from storing further samples, the Next buffer becomes the Current buffer and a new buffer becomes the Next buffer. Digital data samples are then provided from the (previous) Current buffer after it has stopped storing samples.
