AXI memory map read block
Name |
Type |
Range |
Description |
Base address |
uint32 |
Depends on the memory map
|
Specify the base address of registry to read. This port is enabled when the Configure base address and offset from input ports is enabled |
Offset |
uint32 |
Depends on the memory map |
Specify the offset value of registry address. This port is enabled when the Configure base address and offset from input ports and Enable offset are enabled.
If the Enable offset is enabled Memory address = Base address + Offset else Memory address = Base address |
AXI memory map write block
Name |
Type |
Range |
Description |
|||
Base address |
uint32 |
Depends on the memory map
|
Specify the base address of registry to write. This port is enabled when the Configure base address and offset from input ports is enabled |
|||
Offset |
uint32 |
Depends on the memory map |
Specify the offset value of registry address. This port is enabled when the Configure base address and offset from input ports and Enable offset are enabled.
If the Enable offset is enabled Memory address = Base address + Offset else Memory address = Base address |
|||
Value |
|
|
Specify value to write to the given memory address registry |
AXI memory map block behavior
AXI memory map block consists with two modes, read and write. This block is used to read value from the given memory registry address or write to the given memory registry address using memory map via AXI-4 interface.

Typical application
Demo file is provided at:
[<waijung2 installation directory>\waijung2\targets\zynq7000\demo\axi_mm_demo]
To load the model file run the following commands in the Matlab Command Window:
•Demo 1: waijung2.openDemoInCurrentFolder('zynq7000', 'axi_mm_demo1')
