  1. SDR Architectures Bilal Saqib

  2. Software Execution Procedure in SDR 1 • SDR should be compatible with various hardwares and softwares.

  3. Hardware Analog Digital Software Basic Program Radio Function Libraries OS and Device Drivers Application Program Hardware & Software Division 1

  4. Conventional Software Execution Procedure 1

  5. Software Execution Procedure for SDR 1

  6. Single-Chip Architecture for SDR 2 • Hybrid Architecture • Reconfigurable Signal Processors • Accelerators • Additional Hardware Circuits • Programmable State Machine (PSM) • Central Processing Unit (CPU) • Crossbar type Connections • By changing configuration programs of RSP and Accelerator parameters, SDR LSI can be reconfigured to operate with many wireless communication systems.
