Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Accept and hide this message. Technical and de facto standards for wired computer buses. This subset simplifies the design for a bus with a single master. As a workaround, you can group PSELx, and then send the packet to the slave directly.
Views Read Edit View history. Access to the target device is controlled through a MUX non-tristatethereby admitting bus-access to one bus-master at a time.
Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. Computer buses System on a chip.
AVIP for AMBA APB | Cadence IP
APB is designed for low bandwidth control accesses, for example register interfaces on system peripherals. You copied the Doc URL to your clipboard. The AMBA specification defines an on-chip communications standard for designing high-performance embedded microcontrollers. A simple transaction on the AHB consists of an address phase and a subsequent data phase without wait states: Important Information for the Arm website.
APB does not specufication Write Strobe.
AVIP for AMBA APB
You can use APB to interface to peripherals which are low-bandwidth and do not require the high performance of a pipelined bus interface.
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.
Technical documentation is available as a PDF Download.
APB is a non-bursting interface. Was this page helpful? These protocols are today the de facto standard for embedded processor bus architectures because they are well documented and can be used without royalties. The timing aspects and the voltage levels specificstion the bus are not dictated by the specifications.

An important aspect of a SoC is not only which components or blocks it houses, but also how they interconnect.
Error responses are returned to the master. AMBA is a solution for the blocks to interface with each other.
Advanced Microcontroller Bus Architecture – Wikipedia
Signal transitions are sampled at the rising edge of the clock to enable the integration of APB peripherals easily into any design flow.
