The hardware–software partitioning consists of deciding which operations will be executed by the central processing unit (the software) and which ones by specific coprocessors (the hardware). As a matter of fact, the platform selection and the hardware–software partitioning are tightly related operations. For systems requiring little data processing capability, the whole system is implemented in software. If higher performances are necessary, the noncritical operations, as well as control of the operation sequence, are executed by the central processing unit, while the critical ones are implemented within specific coprocessors.
