Title for Topic
APB is a non-bursting interface. Important Information for the Arm website.
Therefore, when you connect a narrower transaction to a wider APB slave, the slave cannot determine which byte lane to write. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.
An important aspect of a Pprotocol is not only which components or blocks it houses, but spscification how they interconnect. You should then connect the slave side of the bridge to any high speed interface protockl connect the master side of the bridge to the APB slaves.
You can use APB to interface to peripherals which are low-bandwidth and do not require the high performance of a pipelined bus interface.
The timing aspects and the voltage levels on the bus are not dictated by the specifications. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices.
Computer buses System on a chip. These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. We appreciate your feedback. It facilitates development of multi-processor designs with large numbers of controllers and peripherals with a bus architecture.
APB Advanced Peripheral Bus interface is optimized for minimal power consumption and reduced interface complexity. Error responses are returned to the master. AMBA is a solution for the blocks to interface with each other.

A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Views Read Edit View history. This subset simplifies the design for a bus with a single master. By disabling cookies, some features of the site will not work. Retrieved from ” https: Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides.
This bus has an address and data phase similar to AHB, but a much reduced, low complexity signal list for example no bursts. Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers.
