The SDK provides the following types of components:

Kseg0 (0x8000 0000 ~ 0x0000)-- The ing between the virtual address and the physical address in this region is very simple. You can directly increase the virtual address by 3 points and zero. However, the MIPs design scheme stipulates that the addresses in this region are all accessed through the cache, so this region is also unavailable before the cache Initialization is set. For systems with MMU, this region address is often used in OS kernel

ACPI (Advanced Configuration Management) is a new type of power management specification proposed by Intel/Microsoft/toshba (Intel, Microsoft, and Toshiba) in 1997, with the intention of giving the system, not the bios, full control of power management, this makes the system more energy-efficient.

first, what is the BIOS
The BIOS is the English "basic Input Output system" abbreviation, after literal translation after the Chinese name is "the basic input to export systems". Its full name should be Rom-bios, which means read-only memory basic input and output system.
Second, the role of Biso
The main functions of the BIOS are as follows:
The first is the Self-Test and initialization program: After the computer is powered on, the system will

When you enable mixed sleep, your computer automatically goes to sleep, however, unlike sleep, the data stored in memory is also stored in the hard drive, so even if the power loss does not result in lost data, and wake-up of the computer can also be faster recovery, which is t

position in an operating system kernel, which is a "pacemaker" that drives an OS kernel to run. Typically, the kernel requires two types of time:
1. Keep a record of the current time and date during the kernel run so that the kernel can make time markers (timestamp, also known as "timestamps") for certain objects and events, or for users to retrieve through time syscall.
2. Maintain a fixed cycle timer to remind the kernel or the user that a period of time has passed.
