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.

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 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： A multi-port serial buffer having a plurality of queues is configured to include a first set of queues assigned to store write data associated with a first port, and a second set of queues assigned to store write data associated with a second port. The available queues are user-assignable to either the first set or the second set. Write operations to the first set of queues can be performed in parallel with write operations to the second programmable set of queues. In addition, a first predetermined set of queues is assigned to the first port for read operations, and a second predetermined set of queues is assigned to the second port for read operations. Data can be read from the first predetermined set of queues to the first port at the same time that data is read from the second predetermined set of queues to the second port.

摘要： In a multi-queue memory system, a plurality of read count pointers (one for each queue) are stored in a read address file, and used to generate empty flags. A read count pointer associated with a first queue is retrieved from the read address file, and it is determined whether the first queue should be available for a re-read operation. If so, the retrieved read count pointer is stored as a first read mark value. The read count pointer is incremented in response to each read operation performed from the first queue, thereby creating an adjusted read count pointer. If a re-read operation is to be performed from the first queue, the first read mark value is stored in the read address file. Otherwise, the adjusted first read count pointer is stored in the read address file. Similar operations are performed on the write side of the multi-queue memory system.
摘要翻译：在多队列存储器系统中，多个读计数指针（每个队列一个）被存储在读地址文件中，并用于产生空标志。从读取地址文件中检索与第一队列相关联的读取计数指针，并且确定第一队列是否应该可用于重新读取操作。如果是这样，检索的读取计数指针被存储为第一读取标记值。读取计数指针响应于从第一队列执行的每个读取操作而增加，从而创建调整的读取计数指针。如果要从第一个队列执行重新读取操作，则第一个读取标记值被存储在读取的地址文件中。否则，调整后的第一读取计数指针存储在读取的地址文件中。在多队列存储器系统的写入侧执行类似的操作。

摘要： A flag logic circuit includes a first comparator configured to generate a first flag value associated with an active read queue of a multi-queue memory device, and a second comparator configured to generate a second flag value associated with an active write queue of the multi-queue memory device. A dual-port memory is adapted to store a flag value for each queue of the multi-queue memory device. The dual-port memory has a first write port configured to receive the first flag value and a second write port configured to receive the second flag value. A first stage storage element is configured to latch each of the flag values stored in the dual-port memory in response to a first clock signal, such that the flag values are synchronized on an active status bus and flag status bus.

摘要： A write counter provides a write count value synchronized with a write clock signal. A read counter provides a read count value synchronized with a read clock signal. The read and write count values are routed through logic, which introduces noise to these values. A first delay circuit generates a first blanking signal, which has a duration corresponding with the duration of the noise introduced to the write count value, in response to the write clock signal. A second delay circuit generates a second blanking signal, which has a duration corresponding with the duration of the noise introduced to the read count value, in response to the second clock signal. The read and write count values are latched into read and write blanking registers, respectively, in response to the first and second blanking signals, respectively, effectively filtering the introduced noise prior to a subsequently performed comparison operation.

The first memory block includes a first array of memory cells, a first sense amplifier circuit and a second sense amplifier circuit. The second memory block includes a second array of memory cells, a third sense amplifier circuit and a fourth sense amplifier circuit. Each of the sense amplifier circuits is independently controlled. Each queue of the multi-queue system has entries in both the first and second memory blocks. A first queue is accessed by alternately accessing the first and second arrays via the first and third sense amplifier circuits. A second queue is subsequently accessed by alternately accessing the first and second arrays via the second and fourth sense amplifier circuits.
