O Amount and type of hardware needed
1. Optimizing the microprocessors, ASIPs and single purpose processors in the system
2. Optimizing according to the performance, power dissipation, cost and other design
பீ Taking into account the design metrics
1. Taking into account the design metrics
2. Design metrics examples —power dissipation, physical size, number of gates and
engineering, prototype development and manufacturing costs
metrics the system
3. Optimizing hardware
Optimizing the Power Dissipation لا
1. Clock Rate Reduction
2. Operating Voltage Reduction
3. Wait Stop and Cache Disable Instructions — Clever real- time programming. Itis by
using of 'Wait' and 'Stop' instructions and disabling or controlling certain units when
not needed is one method of saving power during program execution
[1 Disable use of certain structural units of Disable use of certain
structural units of the processor to reduce power dissipation 0
Process Deadlines
1. Meeting the deadline of all processes in the system while keeping the
memory, power dissipation, processor clock rate and cost at minimum is
a challenge
[1 Flexibility and Upgradeability 1 Reliability
1 Designing reliable product by appropriate design and thorough testing, verification
and validation is a challenge.
