Variable latency method and apparatus for floating-point coprocessor
TL;DR: In this paper, a programmable latency (a programmable number of clock cycles) needed for an operation completion is determined from a formula including the system clock cycle time which the unit will be specified to operate under.
Developing the WTL3 170/3 17 1 Sparc Floating-point Coprocessors
TL;DR: The development of the first two members in a family of scalable-processor-architecture (Sparc)-compatible parts is described, which are the first Sparc chips to integrate all floating-point controller functions, floating- point register files, and 64-b ALU, multiplier, and divide/square-root units in one die.

Microstructural investigation on a rail fracture failure associated with squat defects
TL;DR: In this article , a detailed microstructural analysis was conducted to investigate the causes of squat formation, subsequent crack propagation, transverse defects, and fracture on a railway line, and the abnormal defects are plate martensite with a twin substructure and high carbon content, which could be generated as a result of improper heat treatment during manufacturing of rails.
