    • Access arbiters are used to prioritize read and write access requests to individual memory banks in DRAM memory devices, particularly fast cycle DRAMs. This serves to optimize the memory bandwidth available for the read and the write operations by avoiding consecutive accesses to the same memory bank and by minimizing dead cycles. The arbiter first divides DRAM accesses into write accesses and read accesses. The access requests are divided into accesses per memory bank with a threshold limit imposed on the number of accesses to each memory bank. The write receive packets are rotated among the banks based on the write queue status. The status of the write queue for each memory bank may also be used for system flow control. The arbiter also typically includes the ability to determine access windows based on the status of the command queues, and to perform arbitration on each access window.
    • 访问仲裁器被用于将对DRAM存储器件,特别是快速循环DRAM中的各个存储体的读取和写入访问请求进行优先级排序。 这用于通过避免对同一存储体的连续访问并且通过最小化死循环来优化用于读取和写入操作的存储器带宽。 仲裁器首先将DRAM访问划分为写访问和读访问。 访问请求被划分为每个存储体的访问,并且对每个存储体的访问次数施加了阈值限制。 基于写入队列状态,写入接收数据包在存储体之间旋转。 每个存储体的写入队列的状态也可以用于系统流控制。 仲裁器还通常包括基于命令队列的状态来确定访问窗口的能力,并且在每个访问窗口上执行仲裁。
