The integration of modem controller and data pumpalgorithms into a single RAM-based DSP hardware architecture. These integrated algorithms are stored on the computer' s hard disk, from which they are downloaded into the DSP board' s random access memory (RAM). This downloading, or "booting" process of the PC-installed software algorithms occurs as part of the computer' s power-up initialisation process in less than 100 milliseconds, making it transparent to the user.
