摘要： Output logic generates read requests using a programmable schedule that controls read bandwidth for multiple data streams and stores the read requests in a queuing device. The output logic also dequeues the read requests based on a similar programmable schedule, forwards the read requests to the memory, and reads data units from the memory based on the read requests.
摘要翻译：输出逻辑使用可编程调度来生成读请求，该调度控制多个数据流的读带宽，并将读请求存储在排队设备中。输出逻辑还基于类似的可编程调度使读请求出队，将读请求转发到存储器，并且基于读请求从存储器读取数据单元。

摘要： A system manages a buffer having a group of entries. The system receives information relating to a read request for a memory. The system determines whether an entry in the buffer contains valid information. If the entry is determined to contain valid information, the system transmits the information in the entry in an error message. The system may then store the received information in the entry. In another implementation, the system stores data in one of the entries of the buffer, removes an address corresponding to the one entry from an address list, and starts a timer associated with the one entry. The system also determines whether the timer has exceeded a predetermined value, transferring the data from the one entry when the timer has exceeded the predetermined value, and adds the address back to the address list.
摘要翻译：系统管理具有一组条目的缓冲器。系统接收与存储器的读取请求有关的信息。系统确定缓冲区中的条目是否包含有效信息。如果条目被确定为包含有效信息，则系统将该条目中的信息发送到错误消息中。然后，系统可以将接收到的信息存储在条目中。在另一实现中，系统将数据存储在缓冲器的一个条目中，从地址列表中删除与该条目对应的地址，并启动与该条目相关联的定时器。该系统还确定定时器是否已经超过预定值，当定时器超过预定值时从一个条目传送数据，并将该地址添加回地址列表。

摘要： A method for processing high priority packets and low priority packets in a network device includes performing arbitration on high priority packets until no high priority packets remain. Arbitration then is enabled on low priority packets. A packet size associated with the selected low priority packet is compared with a programmable threshold. Low priority packets are excluded from subsequent arbitration for a programmable duration when the packet size exceeds the programmable threshold.
摘要翻译：一种在网络设备中处理高优先级分组和低优先级分组的方法包括对高优先级分组执行仲裁，直到不存在高优先级分组为止。然后在低优先级数据包上启用仲裁。将与所选择的低优先级分组相关联的分组大小与可编程阈值进行比较。当分组大小超过可编程阈值时，低优先级分组被排除在可编程持续时间的后续仲裁之外。

摘要： Methods and systems consistent with the present invention provide a programmable table which allows software to define a plurality of branching functions, each of which maps a vector of condition codes to a branch offset. This technique allows for a flexible multi-way branching functionality, using a conditional branch outcome table that can be specified by a programmer. Any instruction can specify the evaluation of arbitrary conditional expressions to compute the values for the condition codes, and can choose a particular branching function. When the processor executes the instruction, the processor's arithmetic/logical functional units evaluate the conditional expressions and then the processor performs the branch operation, according to the specified branching function.
