AN720 P RECISION 32™ O P T I MI Z A T I O N C ONSIDERATIONS FOR C ODE S I Z E AND S PEED 1. Introduction The code size and execution speed of a 32-bit MCU project can vary greatly depending on the way the code is written, the toolchain libraries used, and the compiler and linker options. This document addresses how to determine what portions of code are taki.

Features

and code is, providing a relative comparison between various toolchain options and settings. The CoreMark software package cannot be modified except for device-specific information in the portme files. For modes that do not support printf (nohosting libraries), the results were calculated using the value of the variable in code. See the CoreMark website for more information on the test and score reporting requirements (www.coremark.org). www.DataSheet.net/ 4. Non-Toolchain Considerations The coding style and technique can have a great effect on the overall size of the project. 4.1. Coding Te.
