I need help in finding a reference in the literature for a specific circuit. I am willing to trade a microprocessor system in exchange for this information (see below). Consider the following associative memory circuit: ---------------- ----- ---------------- | | C | | | | | |---------| | | | | | |S | | | | | |E | | | | | |L L| | | | CAM | |E O| RS | RAM | | | |C G|-----------| | | ARRAY | |T I| | ARRAY | | | |I C| | | | | |O | | | | | CS |N | | | | |---------| | | | | | | | | | ---------------- ----- ---------------- | S Where: C is the CAM coincidence line from the CAM CS is the CAM word select line from the CAM RS is the RAM word select line to the RAM S is the control line(s) to the selection logic In operation, either the CAM coincidence line (C) or the CAM word select line (CS) from the CAM is allowed to (at least logically) drive the RAM word select line (RS), depending upon the state of the selection control line(s) (S). This is a very straightforward and simple concept. Although the selection logic can be anything from a simple electronic switch to a complex logic network, the simpler the better. I NEED TO FIND AN EARLY (prior to December 1983) PAPER WHICH REFERENCES THIS CIRCUIT IN "THE PUBLISHED LITERATURE". Acceptable sources include books, magazines, journals, defensive publications, theses, proceedings, vendor-published and released hardware manuals, patents, etc. I prefer US documents but many foreign documents will be acceptable. I have been led to suspect that one of the early System 360's (e.g. /67, /85, /95, or /195), with virtual memory and/or caches may have had such a structure. However, many other machines had associative TLM's and caches. THE FIRST PERSON TO PROVIDE REFERENCE TO SUCH A DOCUMENT SHALL RECEIVE A M68332EVS EVALUATION SYSTEM IN TRADE (including all hardware and software, suitable for use with an PC or compatible). I may be able to find satisfactory trades for other non-duplicate documents which meet the above criteria. An independent consultant, Jim Cox, has agreed to judge the submitted articles to see if they meet the above guidelines. Submit your documents using the following procedure: 1) photocopy the article but obliterate the source and date information 2) include information on how to contact you, either by phone, email or USmail 3) FAX THE ARTICLE to Jim at (303) 444-9854 Either Jim or I will contact you for date and publication information after his evaluation. If the document and date are satisfactory, Jim will advise me and arrange the trade. DEADLINE FOR SUBMITTING A REFERENCE IS MIDNIGHT, 31 DECEMBER 1989. If you have questions regarding this request, please contact me at the email address below. William C. Anderson wca@emx.utexas.edu -- William C.
