Abstract
An associative memory system including a plurality of associative data controllers (ADCs) which operate in parallel upon a mass storage including a storage array for each ADC. A primitive function processor (PFP) couples the ADCs to a control unit which provides user access to the system. Hardware instructions are issued by the PFP to the ADCs to enable them to operate in parallel. The ADCs have circuits for performing simultaneous read/write operations with their related storage arrays, and for performing tagging operations, minimum/maximum operations, and logical operations.
