    • 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.

    • 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.
    • 提供了一种用于具有多个队列的多队列存储装置中的标志逻辑电路。 第一级存储器存储多队列存储器设备中的每个队列的标志值。 标志值以下述方式从第一级存储器路由到具有宽度N的标志状态总线。 状态总线控制电路接收识别由多队列存储装置实际使用的队列数M的信号,并且作为响应,生成X个控制值的重复模式,其中X等于(M-(M mod N ))/ N + 1。 响应于X控制值的重复模式,选择器电路将X组N标志值从第一级存储器顺序路由到标志状态总线。 X组N标志值包括与实际使用的队列相关联的标志值。
