• AMBA – 2 AHB overview

    While the APB bus prioritized optimization over performance, as it was intended for modules that didn't require high performance, such as peripherals, the AHB (Advanced High-performance Bus) is a bus focused more on performance. Consequently, it has more signals and its actual operation is more complex.

  • AMBA – 1 APB overview

    AMBA (Advanced Microcontroller Bus Architecture) is a bus protocol developed by ARM. There are several types, but most of them mainly use APB, AHB, and AXI buses.
