We have done our best to make all the documentation and resources available on old versions of Internet Explorer, but vector image support and the layout may not be optimal.

AMBA is a solution for the blocks to interface with each other. The ahhb aspects and the voltage levels on the bus are not dictated by the specifications.

Specificatin are listed by their speed in the protockl ascending order, so the interface at the end of each section should be the fastest. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties.

APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. An important aspect of a SoC is not only which components or blocks it houses, maba also how they interconnect.
