Embedded Edge - October 2001 - Article on Linux

D eveloping a single-processor platform is bad enough. Adding another to the mix could drive even the best developers over the edge, especially when the mix involves a general-purpose processor (GPP) and a DSP. Take heart. A new way of thinking and working allows DSP processes to make operating system calls that are processed by the GPP. Likewise, the operating system running on the GPP can control the processes on the DSP. Allowing standard process creation mechanisms to be used to load and launch DSP processes and allowing DSP processes to make standard A DSP process can behave like any other GPP-based Linux process and access the same Linux kernel system calls and GPP-based hardware.
