Software Platform

Software Layers

The SDAccel runtime software is layered on top of a common low-level software interface 

called the hardware abstraction layer (HAL). The HAL driver provides APIs to runtime 

software which abstract the kernel mode driver details. The 

XDMA and management kernel 

mode drivers interface with

 the memory-mapped platform over PCIe. The following figure 

shows the layers of the Software Platform.

Linux Kernel Mode Drivers

The 

Linux kernel mode drivers are

 included with the SDx Environments installation and are 

developed for the specified address mapping and memory-mapped IP functionality. When 

the platform is implemented as a DSA and used with the SDAccel Environment, the 

hardware abstraction layer (HAL) driver insulates the SDAccel runtime software from the 

implementation details of the kernel mode drivers. 

If you do not use the SDx Environments or the provided HAL driver, you can still interact 

with the memory-mapped IP cores of the platform by using the provided kernel mode 

drivers.

As provided, the Xilinx Acceleration KCU1500 4DDR Expanded Partial Configuration 

platform uses an address map compatible with other Xilinx-provided platforms, so the 

kernel mode drives are not specific to this platform.
