MT7628编程指南.pdf

There are several masters (MIPS 24KEc, USB, PCI Express, SDXC, FE) in the MT7628 SoC on a high performance,

low latency Rbus. In addition, the MT7628 SoC supports lower speed peripherals such as UART Lite, GPIO, I2C

and SPI via a low speed peripheral bus (Pbus). The DDR/DDR2 controller is the only bus slave on the Rbus. It

includes an Advanced Memory Scheduler to arbitrate the requests from bus masters, enhancing the

performance of memory access intensive tasks.
