Will fixed-point arithmetic be worth my trouble?

WebFixed point is widely used in DSP and embedded-systems where often the target processor has no FPU, and fixed point can be implemented reasonably efficiently using an integer ALU. In terms of performance, that is likley to vary depending on … In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cents (1/100 of dollar). More generally, the term may refer to … See more A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit … See more Addition and subtraction To add or subtract two values with the same implicit scaling factor, it is sufficient to add or subtract … See more Explicit support for fixed-point numbers is provided by a few computer languages, notably PL/I, COBOL, Ada, JOVIAL, and Coral 66. They provide fixed-point data types, … See more Various notations have been used to concisely specify the parameters of a fixed-point format. In the following list, f represents the number of fractional bits, m the number of … See more A common use of decimal fixed-point is for storing monetary values, for which the complicated rounding rules of floating-point numbers are often a liability. For example, the open source money management application GnuCash, written in C, switched from … See more Scaling and renormalization Typical processors do not have specific support for fixed-point arithmetic. However, most computers with binary arithmetic have fast bit shift instructions that can multiply or divide an integer by any power of 2; in … See more Decimal fixed point multiplication Suppose there is the following multiplication with 2 fixed point 3 decimal place numbers.

AVX2's widest multiply is 32bit * 32bit => 64bit. AVX512DQ has a 64b * 64b -> 64b (low half) vpmullq, which may show up in Skylake-E (Purley Xeon). AVX512IFMA introduces a 52b * 52b + 64b => 64bit integer FMA.

WebSIMD variables of fixed-point types are supported. GCC can generate instructions from operators on SIMD fixed-point variables. Future Work. 1. Finish the stdfix library. (Pragmas may not be added.) 2. Fine-tuning and optimizations can be added. Right now the expansion of operators just directly generates RTL instructions or calls library functions.
