1.19. Power Management
Intel® Stratix® 10 devices use the advanced Intel 14 nm tri-gate process technology, the all new Intel® Hyperflex™ core architecture to enable Hyper-Folding, power gating, and several optional power reduction techniques to reduce total power consumption by as much as 70% compared to previous generation high-performance Stratix® V devices.
Intel® Stratix® 10 standard power devices (-V) are SmartVID devices. The core voltage supplies (VCC and VCCP) for each SmartVID device must be driven by a PMBus voltage regulator dedicated to that Intel® Stratix® 10 device. Use of a PMBus voltage regulator for each SmartVID (-V) device is mandatory; it is not an option. A code is programmed into each SmartVID device during manufacturing that allows the PMBus voltage regulator to operate at the optimum core voltage to meet the device performance specifications.
With the new Intel® Hyperflex™ core architecture, designs can run 2X faster than previous generation FPGAs. With 2X performance and same required throughput, architects can cut the data path width in half to save power. This optimization is called Hyper-Folding. Additionally, power gating reduces static power of unused resources in the FPGA by powering them down. The Intel® Quartus® Prime software automatically powers down specific unused resource blocks such as DSP and M20K blocks, at configuration time.
The optional power reduction techniques in Intel® Stratix® 10 devices include:
- Available Low Static Power Devices— Intel® Stratix® 10 devices are available with a fixed core voltage that provides lower static power than the SmartVID standard power devices, while maintaining device performance
Furthermore, Intel® Stratix® 10 devices feature Intel’s low power transceivers and include a number of hard IP blocks that not only reduce logic resources but also deliver substantial power savings compared to soft implementations. In general, hard IP blocks consume up to 50% less power than the equivalent soft logic implementations.
