Abstract

A floating-point unit was designed for use with control systems based on Pro-Log four-bit or eight-bit microprocessors. The unit consists of a single board which can be pin-connected into existing control systems. It provides the capability for floating-point arithmetic computations, including operations with transcendental and exponential functions. 9 figures, 2 tables.

Microprocessor-based data acquisition system incorporating a floating-point arithmetic unit for complex mathematical computations. [To determine thickness of conductors on printed wiring boards from measured resistance by use of curve-fitting equations]

Technical Report Hopwood, J

A microprocessor-based, stored-program controller which incorporates a floating-point arithmetic unit to perform complex mathematical computations was developed to determine the thickness of conductors on printed wiring boards. Conductor thickness is calculated from measured resistance by means of curve-fitting equations in the stored program. Called a film thickness calculator, the instrument demonstrates a method which may serve as a basis for other designs involving microprocessor-based data acquisition systems requiring low-speed calculations. 19 figures.
Microprocessor-based system for determining the thickness of conductors on printed wiring boards

Technical Report Hopwood, J

A microprocessor-based, stored-program controller which incorporates a floating-point arithmetic unit to perform complex mathematical computations has been developed to determine the thickness of conductors on printed wiring boards. Conductor thickness is calculated from measured resistance by means of curve-fitting routines in the stored program. Called a film thickness calculator, the instrument provides a rapid, efficient, in-process, nondestructive means for determining plating thicknesses on the surface and in plated-through holes.
Generalization of the proposed IEEE standard for floating-point arithmetic

Conference Cody, W

Several years ago the Microprocessor Standards Committee of the IEEE Computer Society established a Floating-Point Working Group to draft a standard binary floating-point arithmetic on 32-bit microprocessors. As that task neared completion, a second working group was established to generalize the proposed binary standard for other radices and wordlengths. We discuss the emerging generalization, its influence on final deliberations on the proposed binary standard, and the implications for numerical computation.
NDT-COMP9 microcomputer

Technical Report Dodd, C.; Cowan, R.

An 8080-based microcomputer system, the NDT-COMP9, has been designed for instrumentation control and data analysis in eddy-current tests. The NDT-COMP9 represents a significantly more powerful computer system than the NDT-COMP8 microcomputer from which it was developed. The NDT-COMP9 system is contained on a 240- by 120-mm (9.5- by 4.8-in.) circuit board and will fit in a four-wide Nuclear Instrumentation Module (NIM) BIN with 26-pin edge connectors. In addition to the 8080-compatible central processing unit (CPU), an arithmetic processing unit (APU) is available to provide up to 32-bit fixed- or floating-point, basic or transcendental math functions.

Quantifying the Impact of Single Bit Flips on Floating Point Arithmetic

Technical Report Elliott, James; Mueller, Frank; Stoyanov, Miroslav; ...

In high-end computing, the collective surface area, smaller fabrication sizes, and increasing density of components have led to an increase in the number of observed bit flips. If mechanisms are not in place to detect them, such flips produce silent errors, i.e. the code returns a result that deviates from the desired solution by more than the allowed tolerance and the discrepancy cannot be distinguished from the standard numerical error associated with the algorithm. These phenomena are believed to occur more frequently in DRAM, but logic gates, arithmetic units, and other circuits are also susceptible to bit flips. Previous workmore »« less
