摘要： A CAM bank is functionally divided into two or more sub-banks, without replication CAM driver circuits, by disabling all match line discharge circuits in the bank, and selectively enabling the discharge circuits in comprising sub-banks. At least one selectively actuated switching circuit is interposed between the virtual ground node of each discharging comparator in the discharge circuit of a sub-bank and circuit ground. When the switching circuit is in a non-conductive state, the virtual ground node is maintained at a voltage level sufficiently above circuit ground to preclude discharging a connected match line within the CAM access time. When the switching circuit is placed in a conductive state, the virtual ground node is pulled to circuit ground and the connected match line may be discharged by a miscompare. Control signals, which may be decode from address bits, are distributed to the switching circuits to defined the CAM sub-banks.
摘要翻译：通过禁用组中的所有匹配线放电电路，并且选择性地使能包括子组的放电电路，CAM组在功能上被划分为两个或更多个子组，而不需要复制CAM驱动器电路。至少一个选择性致动的切换电路插入在子组的放电电路中的每个放电比较器的虚拟接地节点和电路接地之间。当开关电路处于非导通状态时，虚拟接地节点保持在足够高于电路接地的电压电平，以防止在CAM访问时间内放电连接的匹配线。当开关电路处于导通状态时，虚拟接地节点被拉到电路接地，并且连接的匹配线可能被误比较地放电。可以从地址位解码的控制信号被分配到切换电路以定义CAM子库。

摘要： This invention reduces power consumed during CAM search operations in a CAM/RAM structure utilizing a segmented match line structure. This device is useful when it is known that a portion or portions of the compare data inputs vary infrequently. The apparatus sometimes may be referred to as local match line hold latch, and is a device that stores the value of a local match line comparison result the first time that a search operation occurs, and will stay at that value until the value of the compare data in of the local match line changes.

摘要： The present invention relates to a head restraint assembly providing four-way adjustment and having dual positive stops as well as a single ergonomic control. The present invention includes a frame and a housing that engages a portion of the frame. The present invention further includes a cam assembly disposed within the housing to provide fore/aft adjustment of the housing relative to the frame. The cam assembly includes a camshaft and at least two drum assemblies supported by the camshaft. The cam assembly further includes a contact plate extending parallel to the camshaft to releasably engage the drum assemblies. The camshaft is connected to the contact plate to provide releasable engagement between the contact plate and the drum assemblies. The present invention further includes a control member to engage the cam assembly and provide for fore/aft and vertical adjustment in response to user input.

摘要： The search key and key fields of a CAM in a cache are encoded with a Hamming distance of at least two to increase the speed of the CAM by ensuring each mismatching match line is discharged by at least two transistors in parallel. Where the cache is physically tagged, the search key is a physical address. The page address portion of the physical address is encoded prior to being stored in a TLB. The page offset bits are encoded in parallel with the TLB access, and concatenated with the encoded TLB entry. If a page address addresses a large memory page size, a plurality of corresponding sub-page addresses may be generated, each addressing a smaller page size. These sub-page addresses may be encoded and stored in a micro TLB. The encoded key and key field are tolerant of single-bit soft errors.
摘要翻译：高速缓存中的CAM的搜索键和关键字段通过至少两个汉明距离进行编码，以通过确保每个不匹配的匹配线由并联的至少两个晶体管放电来增加CAM的速度。在缓存物理标记的地方，搜索关键字是物理地址。物理地址的页地址部分在被存储在TLB中之前被编码。页面偏移位与TLB访问并行编码，并与编码的TLB条目连接。如果页面地址满足大的存储器页面大小，则可以生成多个对应的子页面地址，每个地址寻址较小的页面大小。这些子页地址可以被编码并存储在微型TLB中。编码的密钥和密钥字段容忍单位软错误。
