There are multitasking kernels for DSP's, including the 56001, that
are designed for real-time applications.  These kernels guarantee
cycles to the tasks, so you just have to calculate how many cycles
each task needs, and whether the tasks you want to do fit in the cycles
available (minus some overhead for the kernel).

However, you need more than 8Kx24 to do this kind of stuff.
