What is difference between AXI4 and AXI4-Lite?

What is difference between AXI4 and AXI4-Lite?

AXI4: A high performance memory mapped data and address interface. Capable of Burst access to memory mapped devices. AXI4-Lite: A subset of AXI, lacking burst access capability.

What is AXI4-Lite?

AXI4-Lite is a subset of the AXI4 protocol, providing a register-like structure with reduced features and complexity. Notable differences are: all bursts are composed by 1 beat only. all data accesses use the full data bus width, which can be either 32 or 64 bits.

What is AXI4 protocol?

The AXI4 protocol is an update to AXI3 which is designed to enhance the performance and utilization of the interconnect when used by multiple masters. It includes the following enhancements: Support for burst lengths up to 256 beats. Quality of Service signaling.

What is AXI fabric?

The AXI Interconnect is responsible for routing a transaction from a given Master component to the appropriate Slave component (decoding and switching), and ensuring that the various Master component transactions do not interfere with each other (arbitration.) AXI Interconnect Fabric. Features.

What is the difference between AXI and AXI4?

1. AXI3 supports burst lengths up to 16 beats only. While AXI4 supports burst lengths of up to 256 beats. 4.

What is AXI4 peripheral?

The AXI External Peripheral Controller (AXI EPC IP Core) supports data transfers between the AXI4 Interface and external synchronous and/or asynchronous peripheral dices evices such as USB and LAN devices, which have processor interface.

What is the difference between AXI3 and AXI4?

AXI3 supports burst lengths up to 16 beats only. While AXI4 supports burst lengths of up to 256 beats.

What is AXI used for?

AXI in a multi-manager system The AXI protocol defines the signals and timing of the point-to-point connections between manager and subordinates. Note: The AXI protocol is a point-to-point specification, not a bus specification. Therefore, it describes only the signals and timing between interfaces.

What is difference between AXI3 and AXI4?

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 APB interface?

The Advanced Peripheral Bus (APB) is part of the Advanced Microcontroller Bus Architecture (AMBA) protocol family. It defines a low-cost interface that is optimized for minimal power consumption and reduced interface complexity.

What is burst in AXI protocol?

An AXI ‘burst’ is a transaction in which multiple data items are transferred based upon a single address, and it is each data item transferred that is referred to as a ‘beat’.
