An incoming key is broken into a predefined number of sub-keys. Each sub-key is sued to address a Random Access Memory (RAM), one RAM for each sub-key. An output of the RAM is collected for each sub-key, each output comprising a Partial Match Vector (PMV). The PMVs are bitwise ANDed to obtain a value which is provided to a priority encoder to obtain an index. The index is used to access a result RAM to return a result value for the key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for paramaterized application specific integrated circuit (ASIC)/field programmable gate array (FPGA) memory-based ternary content addressable memory (TCAM)","description":"A method and apparatus for providing TCAM functionality in a custom integrated circuit (IC) is presented.
