A patente 6,854,116

Modern applications, such as multimedia applications where text, audio, speech, video, and data communications are all processed in real-time, have special requirements. Standard commercially available microcomputers have typically not had the requisite processing power in order to perform all these tasks in a real-time environment. Modern architectures which are designed to handle the load associated with operating these types of tasks in real-time has sometimes dictated the use of a digital signal processor (DSP). However, even when using a digital signal processor, tasks consuming a lot of processing bandwidth still need to be managed in an efficient way in order for all the requisite processing to be done within specific intervals of time.

Esta patente ter alguma relação com o Cell?

Mas a patente é de 1998. Não estou a ver a relação.

EDIT:interessante...

FIG. 2 illustrates the structure of an operating system which is used for managing tasks and clients using a coprocessor, such as a DSP.
