    • An apparatus comprising a first memory and a second memory. The first memory may be configured read and write words from a data stream comprising a plurality of words in response to (i) a first read enable signal and (ii) a first write enable signal. The second memory may be configured to read and write words from the data stream in response to (i) a second read enable signal and (ii) a second write enable signal. The first and second memories may be configured to read and write alternate words of the data stream.

    • An apparatus comprising a first memory, a second memory, a control circuit and a flag circuit. The first and second memories may each be configured to store data received from a first data input and present data to a first data output. The control circuit may be configured to control data stored in response to a write clock and control data presented in response to a read clock. The flag circuit may be configured to generate one or more composite flags in response to the first memory and the second memory.
    • 一种包括第一存储器,第二存储器,控制电路和标志电路的装置。 第一和第二存储器可以各自被配置为存储从第一数据输入接收的数据并将数据呈现给第一数据输出。 控制电路可以被配置为控制响应于写时钟存储的数据和响应于读时钟呈现的控制数据。 标志电路可以被配置为响应于第一存储器和第二存储器而生成一个或多个复合标志。

    • A method and system for providing hybrid clock distribution is disclosed. The distribution architecture uses a grid distribution at the top level and a balanced buffer tree distribution at the block level. The method includes determining the block layout of an integrated circuit which employs a clock distribution network for distributing clock signals. In addition the method includes providing a mesh distribution network for delivering clock signals to integrated circuit blocks of the integrated circuit. Thereafter, a balanced tree distribution network for delivering clock signals to the components of each block of the integrated circuit is provided. The top level grid provides predictable min/max skew at the top level and the remainder skew budget can be applied to the blocks.
    • 公开了一种用于提供混合时钟分配的方法和系统。 分布架构使用顶层的网格分布和块级别的平衡缓冲树分布。 该方法包括确定采用时钟分配网络来分配时钟信号的集成电路的块布局。 此外,该方法包括提供用于将时钟信号传送到集成电路的集成电路块的网格分配网络。 此后,提供了用于将时钟信号传送到集成电路的每个块的组件的平衡树分配网络。 顶级网格在顶层提供可预测的最小/最大偏移,并且余数偏差预算可以应用于块。
