1. Hardware Overview

RTL8196E – Realtek MIPS core (R3000-class), little-endian, usually @ 400 MHz.
Common chipset combo:

To make OpenWrt run, developers have to use specific toolchains that patch the compiler to avoid these instructions or emulate them in software—a process that introduces overhead and complexity. 2. The "Small RAM" Ceiling
