Abstract:

This report describes an extended-capability content-addressed memory CAM which operates on formatted data bases up to around 10 to the 9th power bits in size. The system, called ECAM, consists of a Control Unit and a serial associative store with logic blocks in the 100-gate complexity range provided at each word. The organization is relatively independent of storage technology the current design assumes charged-coupled device CCD memory organized in 4K-bit words, shifted at a 1-microsecond rate. The Control Unit is microprogrammed to interpret a block-structure query language which operates on logical data structures, such as Codds relations. The mapping of logical structures to operations on physical storage is performed by the hardware. A full repertoire of associative search and arithmetic operators is provided. In its target application, the ECAM will require less than one hour per day to perform a task that was estimated to require between 40 and 700 hours per day on a large commercial mainframe. Author
