System Design of a Cellular APL Computer
Kenneth James Thurber, John W. Myrna · IEEE Transactions on Computers · 1970
A system design is given for a computer capable of efficient execution of APL source statements and programs. The system is organized in a new type computer architecture based upon the storage of matrices and vectors in cellular logic arrays. Almost all of the scalar, mixed, and composite fixed point APL operations are implemented on the machine by algorithms given in this paper. The detailed logical design of the machine has not been completed; however, all the needed logic and memory has been specified. Also, the functions that each hardware cell must be able to perform have been specified. The algorithms for most APL operations are presented in flow charts or tables which give the detailed data flow produced by the execution of each APL operation in the machine.
