摘要： A method and apparatus for congestion and fault management with time-to-live (TTL) have been disclosed. Each time a packet is transferred into an Egress Port's Final Buffer, an associated TTL Timeout Counter will be loaded with a value. If the packet cannot be transferred out of the Egress Port before TTL timeout, it will be purged by removing a memory buffer pointer from the corresponding Virtual Output Queue (VOQ) entry.
摘要翻译：已经公开了具有生存时间（TTL）的拥塞和故障管理的方法和装置。每次将数据包传输到出口端口的最终缓冲区时，相关的TTL超时计数器将加载一个值。如果在TTL超时之前数据包不能从出口端口传出，则通过从对应的虚拟输出队列（VOQ）条目中删除内存缓冲区指针来清除该数据包。

摘要： A multi-queue memory system is configured to operate in a packet mode. Each packet includes a SOP (start of packet) marker and an EOP (end of packet) marker. A packet status bit (PSB), is used to implement the packet mode. The packet status bit enables partial packet write and partial packet read operations, such that a queue switch can be performed in the middle of packet write or packet read operations. The packet status bit also enables data filtering to be performed between an activated EOP marker and a subsequently received SOP marker (i.e., between the end of one packet and the start of the next packet). Packet mark and re-write and packet mark and re-read operations are also enabled.
摘要翻译：多队列存储器系统被配置为以分组模式操作。每个分组包括SOP（分组开始）标记和EOP（分组结束）标记。分组状态位（PSB）用于实现分组模式。分组状态位使得能够进行部分分组写入和部分分组读取操作，使得可以在分组写入或分组读取操作的中间执行队列切换。分组状态位还使得能够在激活的EOP标记和随后接收的SOP标记（即，在一个分组的结束和下一个分组的开始之间）之间执行数据过滤。数据包标记和重写以及数据包标记和重新读取操作也被启用。

摘要： A serial buffer transports packets through queues capable of operating in a packet mode or a raw data mode. In packet mode, entire packets are stored in a queue. In raw data mode, packet header/delimiter information is not stored in the queue (only packet data is stored). Packets can be transferred out of a queue in response to a slave read request. The serial buffer constructs a packet header in response to the slave read request, and retrieves a specified amount of packet data from the selected queue. The serial buffer also transfers out packets as a bus master when a water level exceeds a water mark within a queue. The serial buffer constructs packet headers for these bus master transfers, which may be performed in a flush mode or a non-flush mode (in packet mode), or in a flush mode (in raw data mode).
摘要翻译：串行缓冲区通过能够以分组模式或原始数据模式运行的队列来传输分组。在分组模式下，整个分组存储在队列中。在原始数据模式下，报文头/分隔符信息不存储在队列中（仅存储数据包数据）。响应于从机读请求，可将数据包传送出队列。串行缓冲器构成响应于从读取请求的分组报头，并且从所选队列中检索指定数量的分组数据。当水位超过队列内的水位时，串行缓冲器还将数据包作为总线主机传输。串行缓冲区构建这些总线主机传输的数据包头，可以以冲洗模式或非冲洗模式（分组模式）或冲洗模式（原始数据模式）执行。

摘要： On-chip resources of a serial buffer are accessed using priority packets of a Lite-weight protocol. A priority packet path is provided on the serial buffer to support priority packets. Normal data packets are processed on a normal data packet path, which operates in parallel with the priority packet path. The system resources of the serial buffer can be accessed in response to the priority packets, without blocking the flow of normal data packets. Thus, normal data packets may flow through the serial buffer with the maximum bandwidth supported by the serial interface. The Lite-weight protocol also supports read accesses to queues of the serial buffer (which reside on the normal data packet path). The Lite-weight protocol also supports doorbell commands for status/error reporting.

摘要： A flag logic circuit is provided for use in a multi-queue memory device having a plurality of queues. A first stage memory stores a flag value for each of the queues in the multi-queue memory device. Flag values are routed from the first stage memory to a flag status bus having a width N in the manner described below. A status bus control circuit receives a signal that identifies the number of queues M actually used by the multi-queue memory device, and in response, generates a repeating pattern of X control values, wherein X is equal to (M−(M mod N))/N+1. A selector circuit sequentially routes X sets of N flag values from the first stage memory to the flag status bus in response to the repeating pattern of X control values. The X sets of N flag values include the flag values associated with the queues actually used.

摘要： A multi-queue FIFO memory device that uses existing pins of the device to load a desired number of queues (N) into a queue number register is provided. The queue number register is coupled to a queue size look-up table (LUT), which provides a queue size value in response to the contents of the queue number register. The queue size value indicates the amount of memory (e.g., the number of memory blocks) to be included in each of the N queues. The queue size value is provided to a queue start/end address generator, which automatically generates the start and end address associated with each queue in response to the queue size value. These start and end addresses are stored in queue address register files, which enable proper memory read/write and flag counter operations.
