In view of this it is not surprising that the current generation of “super computers” (i.e., the ILLIAC IV, the STAR 100, and the ASC) all exemplify the use of new architectures to achieve great increases in computing speeds.\u0000 In this paper yet another new architecture is proposed - the inner product computer4. Like the ILLIAC IV it is a “special purpose” processor which is intended to be used in conjunction with a general purpose (i.e., host) computer.","PeriodicalId":72321,"journal":{"name":"ASSETS.

Based on the notation of the tree structures of the Vienna Definition Language [Lu 1], samples of descriptions of context-sensitive grammars are presented as sets of conditionals which operate over the derivation trees of context-free specifications in BNF grammars to eliminate the extra-lingual features. The method is also extended to provide a syntactic specification of the default attributes of a language by the description of modifications which are to be made to the parsed form (syntactic tree) of instances of the language. For the purposes of example, a mini-language (ML 5/2) is presented. This paper exemplifies the problems of parameter passing and provides examples of the context-sensitive conditions of matching procedure calls and their declarations as well as matching parameters and their corresponding arguments.","PeriodicalId":72321,"journal":{"name":"ASSETS.

The programming system includes an interpreter for an intermediate language (IL) into which various source languages (including TRAIL itself) may be translated. The interpreter size is about 1400 bytes.\u0000 The choice of an interpreted target language was guided by the objectives of minimum object code size and machine independence of the developed software. Both of these have been achieved, at the expense of a 20:1 slowdown of execution speed relative to directly assembled code. The interpreted object code is at least 50% smaller than assembly code.\u0000 The source language was designed to match the requirements of language translator software; software design directly models syntax checking, context-free translation, and context-sensitive translation aspects, in ascending order of complexity. Anticipated benefits include greater productivity in design and debug phases, and enhanced communication between programmers via simplified documentation procedures.","PeriodicalId":72321,"journal":{"name":"ASSETS.

A representation of the registers, flip-flops, program counter, subroutine stack, and referenced memory cell is show on the display of the machine. Individual mnemonic instructions may be entered from the keyboard and are shown on the display in standard assembly source language except that instructions may not be labelled. Both the instructions and their operands are syntactically checked character-by-character as they are entered and all illegal entries are refused. The simulator displays the corresponding octal form of these instructions and modifies the representation of the state of the machine accordingly. Short programs of such instructions may be entered and normal sequential execution simulated, Experience indicates that such simulators can provide an easy means of learning the computer organization, mnemonic instructions, and program execution of a computer. They can be especially helpful in demonstrating the dynamics of recursive subroutine calls and push-down stacks.","PeriodicalId":72321,"journal":{"name":"ASSETS.

Generalized splines form a spectrum of functions Sα (that depend on a parameter 0<α<@@@@) which minimize a penalty-type functional (depending on α) associated with a variety of regularization and stabilization methods. Interpolating splines and least-squares splines are obtained as limiting cases of a generalized spline (as α→0 and α&rarr@@@@ respectively). Least-squares solutions (of minimal norm) of operator equations are considered in terms of generalized inverses of linear operators. Approximate minimization (of functionals that arise in these settings) using spline functions is indicated. Projection and least-squares methods (on subspaces of splines for example) are used to approximate least-squares solutions of minimal norm of linear operator equations.","PeriodicalId":72321,"journal":{"name":"ASSETS.
