The STM32 series microcontrollers are 32-bit microcontrollers developed by STMicroelectronics based on the ARM Cortex-M series cores, including several sub-series such as F1, F4, and F7, covering various core architectures like CM0, CM3, and CM4, which can meet different selection requirements. Among them, the F1 series, as a general-purpose type, combines rich peripherals with high … Read more
Once you understand the memory access path, you might wonder: what exactly are the read and write requests sent out by the processor? To clarify this, we need to introduce the bus. Below, I will discuss the ARM’s AXI/ACE bus protocols and the bus structures derived from them. These two protocols are widely used in … Read more
The PCIe bus is designed as an evolution of the PCI bus, and understanding the PCIe bus begins with learning about PCI. The birth of the PCI (Peripheral Component Interconnect) bus is closely related to the rapid development of PCs (Personal Computers). In processor architecture, the PCI bus is categorized as a local bus. The … Read more
In a previous article, we briefly analyzed the architecture of MCU chips.Analysis of MCU chip system architectureIn fact, most WIFI chips can be considered as MCU chips, so the SoC architecture of WIFI chips is basically the same as that of MCU chips, which includes the CPU, bus, peripherals, and of course, the WIFI IP … Read more
1. IntroductionLet’s take a look at a diagramFriends who have read the previous blog post “The Execution Process of CPU Instructions” should have noticed that there is an indispensable component in the execution process of instructions in a computer, which is the bus. The diagram above shows multiple buses, and today we will introduce in … Read more
