User-Mode Extension

Sora provides a new programming model, called User-Mode eXtension (UMX), which allows

user-mode applications to access the radio resources. With UMX APIs, developers can write

baseband processing in user-mode, and therefore the programming and debugging efforts are

greatly reduced.

7.1 UMX Initialization and Configuration

UMX is based on the HWTest driver (see also Chapter 11. ), as shown in Figure 28.

Figure 28. Architecture of Sora UMX.

The UMX application initializes UMX library with SoraUInitUserExtension. The function needs

the device name of the HWTest driver, which is “\\.\HWTest”. HWTest will allocate an abstract

radio from the RCB, and the UMX application can configure the radio parameters using the

corresponding APIs. After the radio is properly configured, the UMX application can start the

radio by calling SoraURadioStart. Before exiting, the SDR application should call

SoraUCleanUserExtension to clean up the resource that has been allocated.
