[Purpose] This study investigated the association between floating toe and toe grip strength. [Subjects and Methods] A total of 635 Japanese children aged 9-11 years participated in this study. Floating toe was evaluated using footprint images, while toe grip strength was measured using a toe grip dynamometer. All 1,270 feet were classified into a floating toe group and a normal toe group accor...

We use reduced precision checking (RPC) to detect errors in floating point arithmetic. Prior work explored RPC for addition and multiplication. In this work, we extend RPC to a complete floating point unit (FPU), including division and square root, and we present precise analyses of the errors undetectable with RPC that show bounds that are smaller than prior work. We implement RPC for a comple...

Due to technological advances, it has become possible to implement floating-point cores on FPGAs in an effort to provide hardware acceleration for the myriad applications that require high performance floating-point arithmetic. However, in order to achieve a high clock rate, these floating-point cores must be deeply pipelined. Due to this deep pipelining and the complexity of floating-point ari...

Cell fate decisions in early embryonic cells are controlled by interactions among developmental regulatory genes. Zebrafish floating head mutants lack a notochord; instead, muscle forms under the neural tube. As shown previously, axial mesoderm in floating head mutant gastrulae fails to maintain expression of notochord genes and instead expresses muscle genes. Zebrafish spadetail mutant gastrul...

This paper presents complete processor hardware with three arithmetic units. The first arithmetic unit can perform 32-bit integer arithmetic operations. The second unit can perform arithmetic operations such as addition, subtraction, multiplication, division, and square root on 32-bit floating point numbers. The third unit can perform arithmetic operations such as addition, subtraction, multipl...

A new generation method to implement CMOS floating resistors is presented. The generation method depends on the linearization of the differential current of two matched NMOS transistors in two alternative configurations. The CMOS floating resistors implemented are based on using MOS transistors operating in the saturation region with their sources connected to their substrates. New CMOS floatin...

The dot product operation is very prevalent in sci-entiic computation and has been incorporated as a primitive operation in some languages. Implementation of the dot product operation by a sequence of IEEE standard multiplications and additions does not prevent substantial error accumulation or warn about catastrophic cancellation. The design of a double precision dot product operation is prese...

Faculty of Engineering, Mathematics and Science Department of Computer Science and Statistics Master of Science in Computer Science Scientific computing with non-standard floating point types May 2015 Author: Vlăduţ Mădălin Druţa Supervisor: Dr. David Gregg This study examined the possible use of non-standard floating point types for scientific computing. The question of this thesis is: “Is the...

It is proposed to add to the C++ standard optional floating-point typedefs having specified widths. The optional typedefs include float16_t, float32_t, float64_t, float128_t, their corresponding least and fast types, and the corresponding maximumwidth type. These are to conform with the corresponding specifications of binary16, binary32, binary64, and binary128 in IEEE_ floating-point format. T...
