Idle Moments are Everywhere!
As chips integrate more features, fewer are in use at any time. Even when a block appears to be busy, much of it is likely idle – at least for a moment. EPUs provide scalable power control so you can partition circuits as finely as desired to isolate and maximize idle time – and minimize energy.
Lightning Fast – and Predictable, too!
Most idle moments are short. But software power managers cannot save energy for idle moments less than 1ms. By moving identification, sequencing and control into hardware, EPUs switch power states 500x faster. Plus, EPUs run in parallel, so wake-up time is deterministic. Beat your deadlines!
Manage Voltage, Power and Clock Together
Most teams separate voltage, power gating, frequency and clock gating control. This leads to overlapping power control schemes and complicates verification. EPUs provide a common architecture for all forms of energy control. Streamline verification. Embrace optimization. Beat your schedule.
Full Optimization with Software Control
Software solutions are slow. Hardware solutions are inflexible. EPUs give you the optimized performance of hardware AND the flexibility of software. Reprogram event conditions to match your use case. Override the hardware to characterize margin. Measure switching rate and duration to avoid thrashing.
