What is the difference between AHB and AXI?
1] AXI is a multi-channel bus with 5 independent channels like Write address channel, Read address channel, Write data channel, Read data channel, Write response channel (Read Response is sent along with the Read data) while AHB is a single channel bus.
Why is AXI faster than AHB?
in which AXI offers performance boost. AXI has completely independent channels for read/write, which enables full duplex mode of data transportation….
| AHB | AXI |
|---|---|
| Low power dissipation | Higher power dissipation. |
| Write Strobes are not supported. | Write Strobes Are supported |
What is AXI protocol?
AXI is an interface specification that defines the interface of IP blocks, rather than the interconnect itself. AXI interconnect interfaces contain the same signals, which makes integration of different IP relatively simple. …
What is AHB protocol?
AHB is a bus protocol introduced in Advanced Microcontroller Bus Architecture version 2 published by ARM Ltd company. In addition to previous release, it has the following features: large bus-widths (64/128/256/512/1024 bit).
What are the advantages of AXI protocol?
Advantages of the AMBA 3 AXI protocol include:
- Independently acknowledged address and data channels.
- Out-of-order completion of bursts.
- Exclusive access (atomic transaction)
- System level cache support.
- Access security support.
- Unaligned address & byte strobe.
- Static burst, which allows bursts to FIFO memory.
- Low power mode.
What is the difference between AHB and AHB Lite?
The AHB-Lite specification differs from the full AHB specification in the following ways: It is a single-master system. There is only one source of address, control, and write data, so no master-to-slave multiplexor is required. There is no arbitration.
What is AHB and APB?
Both Advanced Peripheral Bus (APB) and Advanced High-performance Bus (AHB) are part of Advanced Microcontroller Bus Architecture (AMBA) which is a set of interconnect specifications from ARM that sets protocols for effective on-chip communication between IPs and thereby ensuring high-performance SOC Design.
What is AXI and APB?
The AXI (Advanced eXtensible Interface) to APB (Advanced Peripheral Bus) Bridge translates AXI4-Lite transactions into APB transactions. It functions as a slave on the AXI4-Lite interface and as a master on the APB interface. The AXI to APB Bridge main use model is to connect the APB slaves with AXI masters.
What is difference between AHB and APB?
When talking of the difference between the two, the AHB uses a full duplex parallel communication whereas the APB uses massive memory-I/O accesses. Both the AHB and the APB are on chip Bus standards. The Advanced High-performance Bus is capable of waits, errors and bursts.
What is AHB and APB buses?
AHB stands for Advanced High-performance Bus and APB sands for Advanced Peripheral Bus. Both the Advanced High-performance Bus and the Advanced Peripheral Bus are part of the Advanced Microprocessor Bus Architecture (AMBA). The APB is mainly proposed for connecting to simple peripherals.
What is the AXI capability of data interleaving?
By interleaving the two write data streams, the interconnect can improve system performance. Each AXI channel transfers information in only one direction, and there is no requirement for a fixed relationship between the various channels.
Why is ahb used?
AHB:- It is used for High-Frequency Design and it supports multiple Bus Master, Burst transfer, and pipelined operations. Common AHB Slaves are internal memory devices, external memory interface,s and high bandwidth peripherals.
