Patent
Serial storage interface apparatus for coupling a serial storage mechanism to a data processor input/output bus
TL;DR: In this article, a speed adjustment mechanism was proposed to reduce the amount of data buffering required for interfacing a serial storage mechanism to an asynchronous variable response time I/O bus system.
Patent
Associative file processing method and apparatus
Jerry Duane Dixon,Robert Henry Farrell,Gerald Ulrich Merckel,Jack Dillworth Neely,Stephen Alois Schmitt,William G. Verdoorn,Peter Burghardt Bandy +6 more
TL;DR: In this article, an input/output controller communicates from the host processor to a record scan circuit values of a skip length, a key length and a data length, and a search argument is compared with a length of data specified by the key length value until the end of the record or until a specified number of comparisons has taken place.
Patent
Redundant page identification for a catalogued memory
Jerry Duane Dixon,Robert Henry Farrell,Gerald A. Marazas,Andrew Boyce Mcneill,Gerald Ulrich Merckel +4 more
TL;DR: In this article, a redundant error-detecting addressing code for use in a cache memory is presented, where the blocks are expanded to include redundant addressing information such as the logical data address and the physical cache address.
Patent
I/o controller for multiple disparate serial memories with a cache
TL;DR: In this paper, the authors present an I/O controller for a computer system having a plurality of memory devices of different types such as floppy and hard disks, where a single cache memory is employed for all of the memory devices.
