As competition in the microprocessor market intensifies, the RISC-V instruction set has garnered increasing attention. Although RISC-V is not the first open-source Instruction Set Architecture (ISA), it is the first ISA that allows flexible selection of instruction sets based on actual application scenarios. The RISC-V architecture can accommodate all application scenarios, from high-performance server CPUs … Read more
This example code is derived from the sample code included in the ARM Development Studio: Arm\Development\Studio 2022.0\examples\docs\baremetal_v8. The following is an interpretation based on this type of example, gradually analyzing the implementation logic of bare metal code in conjunction with the characteristics of the ARMv8 architecture. 1. What is Bare Metal Code? Bare Metal code … Read more
For those familiar with computers, the BIOS (that blue interface) may not be too strange, as it is the startup code for the computer. Without BIOS, a computer is destined to be a brick! The BIOS mainly does some preparatory work before booting, such as setting the system time and boot order… but I digress. … Read more
