A Single-Multiplier Quadratic Interpolator for LNS Arithmetic
Linear interpolation requires a single multiplication but is signiicantly less accurate than quadratic interpolation. The latter requires two multiplications. Two novel quadratic interpolation schemes are shown here that approximate the functions required by the Logarithmic Number System (LNS) with more accuracy than linear interpolation using only a single multiplication. One method uses two R...
متن کاملSelf-similar module for FP/LNS arithmetic in high-performance FPGA systems
The scientific community has gratefully embraced floating-point arithmetic to escape the close attention for accuracy and precision required in fixed-point computational styles. Though its deficiencies are well known, the role of the floatingpoint system as standard has kept other number representation systems from coming into practice. The paper discusses the relation between fixed and floatin...
متن کاملComputer Arithmetic Conversions between Binary and Decimal Systems
We will first see how to convert a real number in binary form into its decimal equivalent. The key idea is that the binary digits to the left of the binary decimal point increase in factors of 2 for each place moved over. Similarly, the digits to the right of the binary decimal point decrease in factors of 2 for each place moved over. Consider the real number (101.1)2 in binary form. We have (1...
متن کاملHardware/Software Codesign for Embedded RISC Core
This paper describes hardware/software codesign method of the extendible embedded RISC core VIRGO, which based on MIPS-I instruction set architecture. VIRGO is described by Verilog hardware description language that has five-stage pipeline with shared 32-bit cache/memory interface, and it is controlled by distributed control scheme. Every pipeline stage has one small controller, which controls ...
متن کاملType Systems for Closure Conversions
We consider the problem of analyzing and proving correct simple closure conversion strategies for a higher-order functional language. We specify the conversions as deductive systems, making use of annotated types to provide constraints which guide the construction of the closures. We exploit the ability of deductive systems to specify concisely complex relationships between source terms and clo...
