读写头

This invention discloses a multi-queue sequence buffer management circuit and a method based on a pipeline applying a pipeline structure including: an arbitration circuit selecting one for process from read, write and distribution buffer requests, a buffer slot state module designing state of the slot requiring operation and queue numbers and assigning idle slots, a buffer slot filter module filtering the slot, a buffer slot filter module filtering the slot states not belonging to the current operation queues nor idle aligned in terms of the head pointer, a queue slot selection module computing continuous idle slot numbers from the slot pointed by the head pointer and refreshing the head pointer and selecting preparing slots, a queue slot prior queuing module refreshing the read pointer and result numbers of the current operation queues with the pointer of the first prepare slots and their numbers which can support multi-queue to share one buffer space, queues can access the buffer in overlap.

本发明公开一种基于流水线的多队列顺序化缓冲管理电路及方法，本发明电路采用流水线结构，包括：仲裁电路，从读、写、分配缓冲请求中选取一路进行处理；缓冲槽口状态设置模块，设置请求操作的槽口状态和队列号，分配空闲槽口；缓冲槽口滤除模块，滤除不属于当前操作队列且非空闲态的槽口状态，按头指针对齐；队列槽口选择模块，计算头指针指向槽口起的连续空闲槽口数并更新头指针，选出预备态的槽口；队列槽口优先排队模块，用第一个预备态槽口的指针和预备态槽口数分别更新当前操作队列的读指针和结果数；本发明可以支持多个队列共享一个缓冲空间，各类指令队列能对缓冲进行交叉访问，并对指令结果的写入读出进行顺序化管理。

The magnetic shunt structure prevents magnetic field from the write coil from reaching and affecting the read head.

该磁分路结构防止来自写线圈的磁场到达并影响读头。

Cassette tape: A plastic cartridge which contains 1/4 inch or narrower tape, takeup reel s, and a read/record head pressure pad.

盒带：一个塑胶盒，装有1/4时或更窄的胶带，收带卷轴和写读头压力垫。

盒带：一个塑胶盒，装有1/4时或更窄的胶带，收带卷轴和写读头压力垫。

More specifically the shunt structure prevents magnetic field from the portion of the write coil beyond the back gap from magnetizing a magnetic shield of the read head.

更具体而言，分路结构防止来自超过后间隙的部分写线圈的磁场磁化读头的磁屏蔽件。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
