CASE STUDY
MEDICAL DEVICE PORTING TO CORTEX M4

Scope

Major worldwide infusion pump systems manufacturer hired Auriga to port the infusion pump controlling application from a legacy platform (some of the components of it had reached end of life) to a modern ARM M4 platform, and to a new RTOS.

Achieved Benefits
  • App source tree backward-compatibility with legacy build environment and expected performance provided
  • RTOS specific portions ported to keep the same behavior
  • A modern, energy-efficient solution developed fast and within a reasonable budget
Project Highlights
  • 16-bit x86 CPU to 32-bit Cortex M4
  • Legacy SMX to newer SMX on ARM
  • Porting from x86 Assembler to ARM Assembler
  • New compiler and tools to develop new build environment
  • Legacy unit manual and automated tests executed
  • Close-to-reality hardware prototype built
