    • A programmable logic device (PLD) includes a central processing unit (CPU) and a programmable interface coupled to the CPU, wherein the programmable interface includes a core designated by a user. The programmable interface core allows devices, both on and off-chip, to communicate with the CPU. In one embodiment, the programmable interface core includes a crosspoint switch for coupling a plurality of devices and the CPU. Re-programmability of the PLD provides significant flexibility in providing features that can be parameterized based on the user's needs and/or associated design. Specifically, these parameterized features can be implemented in programmable resources on the PLD, thereby allowing these features to be modified at any time. Moreover, only those resources actually needed for the programmable interface core need be implemented, thereby allowing the user to optimize use of the remainder of the PLD. Finally, the functions of the processor local bus can be efficiently limited, thereby allowing the PLD to approach the performance level of an ASIC.
    • 可编程逻辑器件(PLD)包括中央处理单元(CPU)和耦合到CPU的可编程接口,其中可编程接口包括由用户指定的核心。 可编程接口核心允许芯片上和片外的器件与CPU通信。 在一个实施例中,可编程接口核心包括用于耦合多个设备和CPU的交叉点开关。 PLD的可重新编程在提供可根据用户需求和/或相关设计参数化的功能方面提供了极大的灵活性。 具体来说,这些参数化特征可以在PLD上的可编程资源中实现,从而允许在任何时候修改这些特征。 此外,只有实现可编程接口核心所需的资源才能实现,从而允许用户优化PLD的其余部分的使用。 最后,可以有效地限制处理器局部总线的功能,从而允许PLD接近ASIC的性能水平。
