摘要： A register file method incorporating read-after-write blocking using detection cells provides improved read access times in high performance register files. One or more detection cells identical to the register file cells and located in the register file array are used to control the read operation in the register file by configuring the detection cells to either alternate value at each write or change to a particular value after a write and then detecting when the write has completed by detecting the state change of an active detection cell. The state change detection can be used to delay the leading edge of a read strobe or may be used in the access control logic to delay generation of a next read strobe. The register file thus provides a scalable design that does not have to be tuned for each application and that tracks over voltage and clock skew variation.

摘要： An apparatus and method are disclosed for detecting multiple hits in CAM arrays. A binary address value is stored for each entry of the CAM array and is output to identify the matching entry for a single hit. However, to facilitate multiple hit detection, both the true and complement components of this address are stored and output to determine whether or not a multiple hit occurred. If a multiple hit occurs (e.g., more than one address location has been matched), all the bits that make up the binary address and the complement will not be complements of each other and a multiple hit condition can be detected by XORing each bit of an address location value with the complement of that address location value. If the XORed bits are equal to “1”, then a single hit has occurred. Otherwise, a multiple hit has occurred.
摘要翻译：公开了用于检测CAM阵列中的多个命中的装置和方法。为CAM阵列的每个条目存储二进制地址值，并输出以识别单个命中的匹配条目。然而，为了便于多次命中检测，存储和输出该地址的真实和补码成分，以确定是否发生多次命中。如果发生多重命中（例如，多于一个地址位置已匹配），构成二进制地址和补码的所有位将不会互相补充，并且可以通过将每个位的异或来检测多个命中条件具有该地址位置值的补码的地址位置值。如果异或位等于“1”，则发生单击。否则，发生多重命中。
