    摘要: An integrated circuit contains circuitry to operate in such a fashion to reduce output noise when switching output circuits from a programming mode to a user mode. In an implementation, the integrated circuit (125) is configurable in the programming mode with user configuration data. In the user mode, the integrated circuit will operate with the functionality as defined by the user during the programming mode. When switching from the programming mode to the user mode, each output (210) of the integrated circuit will switch to its user mode value. In order to minimize switching noise, the outputs are released to their user mode values not all at the same time.

    摘要: An integrated circuit with a flexible data strobe signal (DQS) bus structure is presented. The integrated circuit has a number of input/output (I/O) modules with a number of data pins to receive and transmit data. In addition, a subset of the I/O modules also have a data strobe pin. The input/output modules are connected to data strobe signal buses having a fixed configuration. The configuration of the fixed DQS bus groups a number of data pins with a corresponding data strobe pin and the grouping of data pin spans multiple I/O modules. The integrated circuit also has a flexible data bus connected to the I/O modules. Data pins of I/O modules of a second integrated circuit are mapped a subset of the data pins of corresponding I/O modules of the integrated circuit. The flexible data strobe signal bus enables selection of the subset of data pins in the integrated circuit.
