AMBA 3 AHB PROTOCOL SPECIFICATION PDF

Each interface can operate on a separate clock domain and the IP automatically handles all cross clock domain synchronization requirements. This allows a single APB4 Peripheral to be connected directly to the Interface without further logic requirements. Multiple peripherals can share the APB4 Interface through appropriate decoding and multiplexing of the interface signals. The core parameters and configuration options are described in this section. Increasing this parameter reduces the possibility of metastability for signals crossing between the two domains, but at the cost of increased latency.

Increasing this parameter reduces the possibility of metastability for signals crossing between the two domains, but at the cost of increased latency.

All signals are supported. HCLK is the interface system clock. HADDR is the address bus. The HPROT signals provide additional information about the bus transfer and are intended to implement a level of protection. All signals defined in the protocol are supported as described below.

PPROT[] indicates the protection type of the data transfer, with 3 levels of protection supported as follows:. It is used to extend an APB4 transfer. Below are some example implementations for various platforms. All implementations are push button, no effort has been undertaken to reduce area or improve performance.

Resources Below are some example implementations for various platforms. Comments Oct 1. Connected master is not ready to accept data, but intents to continue the current burst.

AHB-Lite to APB Bridge

An option to register the memory output is also provided. The width and depth of the memory, together with an optional registered output stage, are specified via parameters. The IP is designed to easily support a wide range of target technologies, automatically implementing technology-specific memory cells according to the chosen target. A generic behavioural implementation is also supported. Typically a locked transfer is used to ensure that a slave does not perform other operations between the read and write phases of a transaction. The size and implementation style of the memory is defined via HDL parameters.

Advanced Microcontroller Bus Architecture

It facilitates development of multi-processor designs with large numbers of controllers and components with a bus architecture. 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. An important aspect of an SoC is not only which components or blocks it houses, but also how they interconnect.
