After a discussion of the reasons for choosing to implement logic in array form. a detailed description of the nature of array logic is given. Topics specifically discussed include general array structures and implementation, influence of decoder partitioning, design of logic arrays, output phase, “split” variables, feedback in logic arrays, and(More)
IDL is a hardware design language in use in the VLSI environment. It incorporates a significant number of high-level features such as groups, subroutines, and labels and is particularly well adapted to dealing with parallelism at the hardware level. In addition to being human intelligible (and therefore appropriate as a documentation medium), IDL code can(More)

In conventional sputter etching, heterogeneous surfaces are eroded at generally unpredictable rates. The reasons for this are discussed and a solution to the problem is given: Based on control of redeposition, the technique involves the use of a device called a “catcher,” which is placed near the target of the sputtering chamber to trap re-emitted(More)
Hardware design languages (HDLs) allow computer hardware to be described in sufficient detail to be simulated and built, such a description being at a sufficiently high level of abstraction to make the complete design readily intelligible to anyone skilled in that language. A number of HDLs have been developed and are in use in IBM. To date, no overwhelming(More)
