摘要： A method and apparatus for implementing virtual memory having multiple selected page sizes are provided. A virtual address includes a map index and a frame offset. A selector mechanism receives the virtual address frame offset and generates an offset and index. A frame map table indexes the virtual address map index and the selector generated index and generates a base address. The frame map table generated base address and the selector generated offset are combined to provide a physical address.

摘要： A method and apparatus are provided for resource allocation with guarantees. A resource allocator is coupled to a controller. The resource allocator allocates resources between a plurality of arrival processes. A dedicated resource pool and a shared resource pool are provided. When an arrival process is identified, the resource allocator obtains a predefined characterizing value for the identified arrival process. Responsive to the obtained predefined characterizing value, resource from one of the dedicated resource pool or the shared resource pool is allocated to the arrival process. The controller is utilized for tracking resource use and for providing the predefined characterizing value for each of the plurality of arrival processes. The dedicated resource pool has a predetermined capacity greater than or equal to the total of all the low threshold values for each of the arrival processes. The dedicated resource pool provides the guarantees with the shared pool providing statistical multiplexed resource use. The controller increments a usage charge for the arrival process when a resource is allocated and decrements the usage charge at the end of use of the allocated resource. The controller evaluates use for the identified arrival process and updates the predefined characterizing value.

摘要： A network buffer memory is divided into pools of locations including a plurality of tinygram contiguous sections and a plurality of jumbogram contiguous sections. The tinygram contiguous sections available for storage of packets are listed in a list of tinygram pointers. The jumbogram contiguous sections available for storage of packets are also listed in a list of jumbogram pointers. A threshold for distinguishing the packets as tinygrams and jumbograms is programmed. As packets are received, they are measured against the threshold. Responsive to detection of an end of packet condition prior to reaching the threshold, storing the packet in a tinygram contiguous section. Otherwise, the packet is stored in a jumbogram contiguous section. Availability of sections is determined by query to the FIFO lists of pointers.

摘要： A method and apparatus are provided for enhanced scatter mode allowing user data to be page aligned in a memory. An adapter is coupled between a data communications network and the memory. A data packet including protocol header bytes is received from a data communications network by the adapter. A variable amount of data is specified for a first scatter page that contains the protocol header bytes. Subsequent sequential pages from the received data packet are transferred, for example, by direct memory access (DMA) operations, to real page addresses in the memory with the sequential pages transferred being page aligned in the memory. A page address is written to a DMA list stored in an adapter memory for the sequential pages transferred. A count value is incremented in a packet header of a number of pages transferred for each sequential page transferred. Responsive to transferring a last page from the received data packet, the first scatter page containing the packet header, the DMA list and the protocol header bytes is transferred to a separate address space in the memory. A small packet or single page size is specified for the adapter. When the total data size of a received packet is less than this small packet size, then the packet is not scattered. A single page mode is performed to transfer the small packet to the memory.

摘要： The present invention is a method and apparatus for reducing processing overhead using a stream data reassembly mechanism and at least one data buffer. The present invention pre-processes incoming frames before delivering the frames to system memory. When a first packet of an data stream is received, the data from the packet is placed into a data buffer. Information about the first packet is stored in a logical channel descriptor (LCD) to indicate that data exists in the current data buffer. As each subsequent packet in the data stream is received, the reassembly mechanism removes extraneous transmission data from the packet and checks the CRC of each trailer to qualify the data within the packet. After the data is qualified, the reassembly mechanism stores the data portion of the packet in the data buffer. This preprocessing of each packet continues until a predetermined condition is met. Once a predetermined condition is met, the reassembly mechanism will make the contents of the buffer available to the system. The reassembly may optionally associate a direct memory access (DMA) descriptor with the buffer and burst the contents of the buffer into system memory. The reassembly mechanism of the present invention thereby reduces the amount of data reception interrupts processed by the system and can also reduce the number of direct memory access data transfer across the system bus.
摘要翻译：本发明是一种使用流数据重组机构和至少一个数据缓冲器来减少处理开销的方法和装置。本发明在将帧传送到系统存储器之前预处理输入帧。当接收到数据流的第一分组时，来自分组的数据被放入数据缓冲器中。关于第一分组的信息被存储在逻辑信道描述符（LCD）中以指示数据存在于当前数据缓冲器中。当接收到数据流中的每个随后的分组时，重新组装机制从分组中去除无关的传输数据，并且检查每个预告片的CRC以对分组内的数据进行限定。数据合格后，重组机制将数据包的数据部分存储在数据缓冲器中。每个分组的这种预处理持续到满足预定条件。一旦满足预定条件，重新组装机制将使缓冲区的内容可用于系统。重组可以可选地将直接存储器访问（DMA）描述符与缓冲器关联并将缓冲器的内容突发到系统存储器中。因此，本发明的重新组装机构减少了系统处理的数据接收中断量，并且还可以减少跨系统总线的直接存储器访问数据传输的数量。

摘要： A method and apparatus processing system for enhancing the processing of a plurality of related packets received at a logical unit within a data processing system are disclosed. A plurality of packets are received at the logical unit. Then each of the plurality of packets are examined and a session identification is obtained for each of the plurality of packets. During a preselected time window, each of the plurality of packets are associated with a group. Each packet in a group has a session identification that is identical to every other packet within the group.
