2. MTK not only includes SDE, but also other tools and libraries to accelerate the development of high-quality, high-performance applications that run on the
TLB Miss is the core process of memory management in MIPS. In the previous article on MIPS, TLB miss related principles, this article focuses on the Linux kernel code implementation. TLB Refill Initialization
In the kernel boot process, the TLB refill exception is initialized and the corresponding processing interface is set. The main processes are as follows (take r3k as an example):

Explanation of the MIPS architecture Linux trojan for vromips
Most Windows operating systems are installed on PCs of individual users, while Linux systems are widely used on servers. Therefore, Linux systems have fewer Trojans than Windows systems. Due to the application limitations of the MIPS architecture, Linux trojans on the MIPS architecture are rare.

For the development of a CPU, it is very important to master the register conventions of the CPU in which it works.
The MIPS architecture provides 32 GPR (general purpose register ). The usage of these 32 registers is roughly as follows:
