Executing application code from RAM on the MAXQ8913 microcontroller

Posted: 16 Sep 2009     Print Version  Bookmark and Share

Keywords:SRAM  microcontroller MAXQ8913  application code 

The Harvard memory map architecture used by the MAXQ8913 and other MAXQ microcontrollers provides users with the flexibility to map different physical memory segments (such as the data SRAM) into either program or data memory space, as needed. Under certain circumstances, executing portions of an application from data SRAM can provide a performance boost and reduce power consumption. These benefits come at the cost of additional application complexity.

This application note explains how to configure and load assembly-based code so that it will execute properly from the internal SRAM. The advantages and disadvantages of this execution are discussed. Demonstration code for this application note is written for the MAXQ8913, using the assembly-based MAX-IDE environment.
