ALOE Project

The ALOE project develops an open-source SDR framework with cognitive resource management capabilities. Its mission is creating a modular framework that eases the design and integration of software modules (waveform components) and their deployment on multiprocessor execution environments while enabling waveform portability and distributed real-time execution. ...

ALOE is being written in plain C and VHDL for programmable and non-programmable devices respectively. Although their implementation is completely different, its functionality as middleware remains. The ALOE-C and ALOE-VHDL implements a reduced set of functions and services but its modular architecture allows and easy extension.

ALOE-C

The design of ALOE in C has been thought to be easily scalable and flexible. Only one small part (ALOE Hardware API) has to be rewritten when porting the system from one platform to another. So, most of ALOE functions (Software Daemons) are identical for all programmable devices where a C compiler is available.

Currently, two versions of the ALOE Hardware API are available, for Linux 2.6 and Texas Instruments DSP/BIOS Operating Systems. Although both platforms are able to run any Daemon, the common configuration maps the manager daemons (SWMAN, HWMAN, STATSMAN, CMDMAN) to the Linux platforms, leaving the DSP to perform more specialized and necessary tasks.

ALOE for Texas Instruments(c) DSP C6000 family

ALOE version for TI DSP's works on DSP/BIOS(c) for C6000 platforms. It obviously requires this OS which we cannot provide.

Develope Waveforms for ALOE

Writing waveforms for ALOE is independent of the platform where it will be executed however, we recommend to perform the debugging and first phases of the development on a Linux platform as it is much more comfortable. Once you are sure that it works and it does what is supposed to, you can just re-build it for the DSP platform (linking with the HW API for DSP) and it should just 'work';
