A hardware-integrated GPC/search memory

Abstract

A search memory that can be operated in conjunction with a USQ--20 computer using only the standard input-output channels is being developed by Goodyear Aerospace Corporation. This approach is referred to as the peripheral search memory. On the other extreme, there is the possibility of completely integrating the search memory with the USQ--20 computer. That is, the instruction repertoire can be modified to include associative instructions, the control logic can be modified extensively, and additional registers can be added as necessary. Neither integration can be considered the optimum since the latter involves costs that are out of proportion with the advantages, and the former involves undue transfer time penalties and more complex programming.
