Abstract
This article is related to code generation for floating-point arithmetics in the MIPS architecture. This work is a part of the «RuC» project. It is specialized only in code generation for operations with floatting-point numbers. This paper does not consider lexical, syntactic, and species-specific analyses.
Highlights
RISC and CISC architectures, unlike stack architectures and virtual machines systems, have different ways to express high-level language features

In the MIPS32 architecture, function parameter values must be in some specific registers, and function values must be in other specific registers
Summary
RISC and CISC architectures, unlike stack architectures and virtual machines systems, have different ways to express high-level language features. There are many registers for working with data, which creates a large variability in optimal code generation. Code generation in these architectures is quite a difficult task. For work with such architectures, a technique of request and response [1] have been developed at the mathematics and mechanics faculty of the Leningrad State University: from the top of the constructed parse tree the requests for values are received, and from below the answers – form submission parse (register, memory, constant). The left operand of a binary formula must be represented in a stored register if the right operand has calls or slicing that apply the same rules as functions, otherwise the left operand can be represented
