    摘要: A phase reversal detector comprises a circuit for receiving an input signal subject to occasional phase reversals, a circuit for generating signals representing the quadrature components thereof, and a circuit responsive to a migration in the quadrature plane of the position of the quadrature components by an amount greater than a predetermined threshold to generate a signal indicative of a valid phase reversal. The detector is capable of exceeding the requirements of ITU standard G.165, and yet is simple to implement and works over a large dynamic range.

    摘要: A distributed architecture parallel processing apparatus, includes a central microprocessor having at least one external interface connected to a similar interface of a neighboring parallel processor. The processors exchange data and control signals through the interfaces to cooperatively share in the execution of a program. An inter-processor status register in each processor maintains the current status of the processors.
