These benefits become especially important in fanless systems.

Software Migration Complexity

Hardware selection represents only part of the replacement process.

Operating System Migration

Many Zynq UltraScale+ systems utilize:

• Linux

• Yocto

• FreeRTOS

• Custom RTOS implementations

Migration complexity varies significantly depending on platform architecture.

Development Environment Comparison

Development environment familiarity often affects project schedules as much as hardware architecture.
