Document directory SRAM DRAM Prom EPROM EEPROM I recently used several types of memory, but it will always be mixed up. So I found the characteristics of various types of memory on the Internet and sorted it out for future use. Memory by purpose can be divided into external memory and internal memory. External Storage is usually a magnetic medium or a CD, which can store information for a long time. Memory refers to the storage part on the mo

Level one cache is in the same instruction cycle as the CPU. For example, view the cache for the current system. DMIDECODE-T Cache # Dmidecode 2.9SMBIOS 2.6 present.

forming a hardware system. On-Chip Bus standard advanced microcontroller bus structure AMBA defines communication standards for high-performance embedded microcontroller. Three bus groups are defined: AHB (AMBA High Performance Bus), ASB (AMBA System Bus), and APB (AMBA Peripheral Bus ). AHB Bus is used for high-performance, high-clock operating frequency modules. AHB provides interfaces for high-performance processors, on-chip memory, and off-chip memory, while bridging slow peripherals. DMA,

1.1 embedded processor s3c2440a [17] S3c2440a is a dedicated chip designed mainly for handheld devices. It features low power consumption and high-speed processing and computing capabilities. To reduce system consumption, 2440 uses the following components: 2440 Based on the ARM920T kernel, 0.13um CMOS standard unit and storage unit complex, its power consumption and small, simple, and stable design are very suitable for products with high power requirements. S3c2440a adopts the ARM920T kernel a

bus interfaces shown in the diagram of S3c2410. Note that the peripherals connected to the two bus are different. AHB Bus connects high-speed peripherals, while low-speed peripherals are connected through APB bus. Obviously, different clock signals should be used for peripherals on different bus. AHB Bus corresponds to hclk and APB bus corresponds to pclk. So we should know in advance that the peripherals corresponding to each bus have those, so that after the clock signal is set, the initializ
