摘要： String matching a first string to a string stored in a string dictionary is performed by k-way hashing the first string and locating corresponding k hash locations in a first memory. When any of the k hash locations has a zero Bloom bit, the first string is deemed to not match any of the strings in the string dictionary. Otherwise, a sub-set of the k hash locations identified as those k hash locations having non-zero Bloom bits and a unique bit set to 1 each include a pointer that points to a string in the string dictionary that is fetched and compared to the first string wherein the fetches from the string dictionary are interleaved over the addresses from the first memory. A match signal is issued when the first string matches at least one of the strings stored in the dictionary.
摘要翻译：将第一个字符串与存储在字符串字典中的字符串进行匹配的字符串通过k-way散列第一个字符串并在第一个存储器中定位相应的k个哈希位置来执行。当k个哈希位置中的任何一个具有零布隆比特时，第一个字符串被认为与字符串字典中的任何字符串不匹配。否则，被识别为具有非零布隆比特的k个哈希位置和设置为1的唯一比特的k个哈希位置的子集包括指向字符串字典中的字符串的指针，该字符串被提取并与第一个字符串，其中来自字符串字典的提取被交织在来自第一存储器的地址上。当第一个字符串匹配字典中存储的字符串中的至少一个字符串时，发出匹配信号。

摘要： An efficient finite state machine implementation of a string matching that relies upon a Content Addressable Memory (CAM) or a CAM-equivalent collision-free hash-based lookup architecture with zero false positives used as a method for implementing large FSMs in hardware using a collision-free hash-based look up scheme with low average case bandwidth and power requirements that overcomes prior art limitations by providing the ability to match an anchored or unanchored input stream against a large dictionary of long and arbitrary length strings at line speed. It should be noted that in the context of the described embodiments, a string could take many forms, such as a set of characters, bits, numbers or any combination thereof.

摘要： An ion wind fan can be incorporated into a solid-state lighting device to thermally manage the lighting device. In one embodiment, the lighting device includes a bulb body having air intake and exhaust openings, and an ion wind fan to generate airflow between the openings. The lighting device can further include an upstream heat sink disposed upstream of the ion wind fan with respect to the airflow, the upstream heat sink having a shape that provides no direct line of sight from the air intake openings to the ion wind fan.
