The difference between S3C2440, S3C2450 and S3C6410 in arm920t

　　Samsung currently launches the S3C6400 and S3C6410, both of which are based on the ARM architecture and have compatible hardware pins. It should be said that the general functions are basically the same. The obvious difference is that the S3C6410 comes with 2D/3D hardware acceleration.

　　S3C2440 is actually a very good CPU. It is cheap and has many internal resources. Most importantly, it is used by many people in China and there is a lot of relevant information. ARM920T core, 400M main frequency, supports NAND FLASH, NORFLASH, SDRAM, supports STN/TFT LCD, 4-channel DMA, 3-channel UART, 2-channel SPI, IIC bus, IIS/AC97 audio controller, SD/MMC controller, 2 Channel USB HOST 1-channel USB DEVICE, 4-channel PWM, 8-channel A/D conversion, touch screen controller, RTC, CMOS camera, multi-function IO and various power management.

　　The difference between S3C2440, S3C2450 and S3C6410

　　As the main solution processor provider for handheld devices such as GPS, PDA, and digital TV, South Korea's Sumsung Company has recently launched new ARM processor S3C2450 and S3C6410 chips. What are the differences and advantages between these platforms and the S3C2440 processor?

　　S3C2440:

　　Main frequency 400MHz;

　　SDRAM memory controller;

　　Support Nor Flash and Nand Flash (SLC)

　　Supports 2 types of Flash startup;

　　Internal LCD, I2C, Camera and other controllers.

　　S3C2450:

　　Main frequency 533MHz;

　　Dual bus architecture, one for memory bus and one for Flash bus;

　　DDRII memory and DDR memory controller;

　　Supports both Nor Flash and Nand Flash. Nand Flash supports both SLC and MLC architectures, thus greatly expanding storage space;

　　Supports multiple startup methods: mainly including SD, Nand Flash, Nor Flash and OneFlash device startup

　　8 DMA channels, including LCD, UART, Camera and other dedicated DMA channels;

　　USB2.0 slave device controller;

　　Internal LCD, I2C, Camera and other controllers.

　　S3C6410:

　　Main frequency 800MHz;

　　Dual bus architecture, one for memory bus and one for Flash bus;

　　DDR memory controller;

　　Supports both Nor Flash and Nand Flash. Nand Flash supports both SLC and MLC architectures, thus greatly expanding storage space;

　　Supports multiple startup methods: mainly including SD, Nand Flash, Nor Flash and OneFlash device startup

　　8 DMA channels, including LCD, UART, Camera and other dedicated DMA channels;

　　USB2.0 OTG controller;

　　Internal video decoder, including MPEG4, H.264, H.263 and other video formats;

　　Internal video accelerator, including 2D and 3D processing.

　　Tvout and S-Video output.

　　Internal LCD, UART, SPI, I2C, Camera, GPIO and other controllers;

　　Based on S3C2440, in addition to increasing the main frequency, S3C2450 mainly adds DDR control and MLC architecture Nand Flash controller. These are mainly used to improve product processing speed and increase storage space, thereby giving end users a superior performance experience. In addition to the above functions, S3C6410 also adds USB 2.0 OTG controller, video hardware decoding and 2D, 3D accelerator and other functions to give users more powerful and free application space and more multimedia visual experience. At the same time, taking into account product mass production and upgrade, both S3C2450 and S3C6410 processors support SD card startup mode, which greatly facilitates the production and burning steps.
