  • Patent number: 8160192
    Abstract: A clock and data recovery (CDR) system and method for recovering timing information and data from a serial data stream. The CDR system includes a sampling circuit that produces a recovered clock/data signal and an interleaving feedback network that provides feedback to the sampling circuit. The feedback network includes a logic circuit that produces control signals based on the recovered clock/data signal, a first multiplexer that selects from four phases of a global clock signal based on a control signal, a first delay-locked loop having a first set of delay cells coupled to a second multiplexer that produces a delayed signal based on the selected global clock signal, and a second delay-locked loop having a second set of delay cells that produces a set of phase-shifted feedback signals that are applied to the sampling circuit to phase-align the sampling circuit with the transitions in the received serial data stream.

  • Patent number: 7949863
    Abstract: A method and system for inter-port communication utilizing a multi-port memory device. The memory device contains an interrupt register, an interrupt signal interface (e.g., a dedicated pin), an interrupt mask, and one or more message buffers associated with each port. When a first component coupled to a first port of the memory device wants to communicate with a second component coupled to a second port of the memory device, the first component writes a message to a message buffer associated with the second port. An interrupt in the input register of the second port is set to notify the second component coupled to the second port that a new message is available. Upon receiving the interrupt, the second component reads the interrupt register to determine the nature of the interrupt. The second component then reads the message from the message buffer.

  • Patent number: 7908501
    Abstract: A method and system for progressively reducing the power consumption of a serial memory device is provided, called the power control system. The power control system monitors the ports of a multi-port serial memory so that they can be enabled or disabled on a per-port basis. When data is not being transmitted or received on a port, a series of steps are taken to progressively de-power portions of the port and cause the port to enter into a low-power state. By disabling certain ports and placing ports in a low-power state, the power consumption of the overall serial port memory is significantly reduced.

  • Patent number: 7639561
    Abstract: A multi-port memory device having two or more ports wherein each port may operate at a different speed. The multi-port memory device contains memory banks that may be accessed via the two or more ports. Two clock signals are applied to each port: a system clock and a port clock. The system clock is applied to port logic that interfaces with the memory banks so that the ports all operate at a common speed with respect to the memory banks. The port clock is applied to a clock divider circuit that is associated with each port. The port clock is divided to a desired frequency or kept at its original frequency. Such a configuration allows the ports to operate at different speeds that may be set on a port-by-port basis.
