Digital Signal Processing Microprocessors, Software and Applications
2. Motivation of SDR
Notes to Figure 1:
1) The system uses a generic hardware platform with programmable modules (DSPs, FPGAs, microprocessors) and analog RF modules. The operating environment performs hardware resource management activities like allocation of hardware resources to different applications, memory management, interrupt servicing and providing a consistent interface to hardware modules for use by applications.
2) In SDR system, the software modules that implement link-layer protocols and modulation/demodulation operations are called radio applications and these applications provide link-layer services to higher layer communication protocols such as WAP and TCP/IP.
