    • A system and method for limiting the size of a local storage of a processor are provided. A facility is provided in association with a processor for setting a local storage size limit. This facility is a privileged facility and can only be accessed by the operating system running on a control processor in the multiprocessor system or the associated processor itself. The operating system sets the value stored in the local storage limit register when the operating system initializes a context switch in the processor. When the processor accesses the local storage using a request address, the local storage address corresponding to the request address is compared against the local storage limit size value in order to determine if the local storage address, or a modulo of the local storage address, is used to access the local storage.
    • 提供了用于限制处理器的本地存储器的大小的系统和方法。 与用于设置本地存储大小限制的处理器相关联地提供设施。 该设施是一种特权设施,只能由在多处理器系统或相关处理器本身的控制处理器上运行的操作系统访问。 当操作系统初始化处理器中的上下文切换时,操作系统设置存储在本地存储限制寄存器中的值。 当处理器使用请求地址访问本地存储器时,将与请求地址相对应的本地存储地址与本地存储限制大小值进行比较,以便确定本地存储地址或本地存储地址的模数是否为 用于访问本地存储。

    • A system and method for communicating with a processor event facility are provided. The system and method make use of a channel interface as the primary mechanism for communicating with the processor event facility. The channel interface provides channels for communicating with processor facilities, memory flow control facilities, machine state registers, and external processor interrupt facilities, for example. These channels may be designated as blocking or non-blocking. With blocking channels, when no data is available to be read from the corresponding registers, or there is no space available to write to the corresponding registers, the processor is placed in a low power “stall” state. The processor is automatically awakened, via communication across the blocking channel, when data becomes available or space is freed. Thus, the channels of the present invention permit the processor to stay in a low power state.
    • 提供了一种用于与处理器事件设施进行通信的系统和方法。 系统和方法利用通道接口作为与处理器事件设施通信的主要机制。 通道接口例如提供用于与处理器设备,存储器流控制设备,机器状态寄存器和外部处理器中断设备进行通信的通道。 这些通道可以被指定为阻塞或非阻塞。 使用阻塞通道,当没有数据可用于从相应的寄存器读取时,或没有可用空间写入对应的寄存器时,处理器处于低功耗“停止”状态。 当数据可用或空间被释放时,通过阻塞通道的通信自动唤醒处理器。 因此,本发明的通道允许处理器保持在低功率状态。

    • A buffer, a method, and a computer program product for DMA transfers are provided that are designed to save memory space within a local memory of a processor. The buffer is a return buffer with a portion reserved for DMA lists. A DMA controller accomplishes DMA transfers by: reading address elements from a DMA list located in the DMA list portion; reading the corresponding data from system memory; and copying the corresponding data to the return buffer portion. This buffer saves space because when the buffer begins to fill up the corresponding return data can overwrite the data in the DMA list. Accordingly, the DMA list overlays on top of the return buffer, such that the return data can destruct the DMA list and the extra storage space for the DMA list is saved.
    • 提供了用于DMA传输的缓冲器,方法和计算机程序产品,其被设计为在处理器的本地存储器内节省存储器空间。 缓冲区是具有为DMA列表保留的部分的返回缓冲区。 DMA控制器通过以下方式完成DMA传输:从位于DMA列表部分的DMA列表读取地址元素; 从系统内存读取相应的数据; 并将相应的数据复制到返回缓冲器部分。 此缓冲区可节省空间,因为当缓冲区开始填满相应的返回数据时,可以覆盖DMA列表中的数据。 因此,DMA列表覆盖在返回缓冲器的顶部,使得返回数据可以破坏DMA列表,并且保存DMA列表的额外的存储空间。
