MIPS is a shining star in high efficiency, low-power CPU design principles and has been in the mobile and embedded industries for nearly 30 years. This article will quickly explore the evolution of the MIPS architecture and describe how it evolved from the earliest version of Stanford University's Computational Science lab to the current architecture.
You may have heard about Google TV that is coming soon in our homes, through Android set-top boxes. it's expected to come out this fall, but the source code of the MIPs port is already available to the public. it is important to note that android was originally designed for smartphones, which commonly use arm processors. however, in the set-top box market, MIPS-based systems are quite popular. this is why t

I will upload my new book "Write CPU by myself" (not published yet). Today is 13th articles. I try to write them every Thursday.
4.4 create the MIPs compiling environment
The openmips processor is designed to be compatible with the mips32 instruction set architecture. Therefore, you can use the existing GNU development tool chain under the mips32 architecture. This section describes how to install and use the GNU development tool chain and how to cre
After the system starts power-on, the default program entry of the MIPs processor is 0xbfc00000. The address is in the address area of kseg1 without caching, and the corresponding physical address is 0x1fc00000, that is, the CPU starts to get the first command from 0x1fc00000. This address has been determined as the flash location on the hardware. bootloader copies the Linux kernel image to a idle address in Ram, there is usually a memory movement ope

Overview: This project needs to operate the embedded database SQLite on multiple platforms (MIPS must support), while the newest Sqlite-jdbc-3.15.1.jar Local drive contains only a small number of platforms, thus solving the support MIPS platform is really necessary. There are many ways to do this, specifically as follows. 1.1 SQLite three ty
1. Kernel stack Switching (MIPS)
When a dispatch switches to a process, the *KERNELSP is set based on the value of the task_struct->thread_info (the bottom of the kernel stack of the process currently running), and the value is Thread_info + thread_size-32 (MIPS, using SET_SAVED_SP macros).

No need to change, who will go to see it. 2 context switching is a processor-related process, the so-called context is generally referred to as the CPU registers, and each processor register is different, the switching action is not the same, this article takes MIPS as an example to explain. 3 Embedded appl
