4.6. Conclusions
A close examination of contemporary general-purpose embedded processors reveals an underlying structure similar to (albeit simpler than) the structure of their high-performance desktop cousins. We believe this has to do with a common foundation grounded in general-purpose ISAs and the resulting confinement to generic instruction-level pipelining. Moreover, the evolution of embedded processors seems to parallel that of desktop processors, as more high-performance pipelining techniques are gradually deployed within successive generations of embedded processors.
This evolution has created a tension between higher performance and the need for deterministic performance. Currently, this tension is reconciled by dual offerings: on the ...
