Power Consumption Optimization Techniques.
Posted: Tue May 13, 2025 11:02 pm
I'm working on a project that requires extremely low power consumption with a QuickLogic FPGA. I'm using an EOS S3 and aiming for battery-powered operation. I've already implemented clock gating and voltage scaling where possible.
I'm looking for advice and best practices on further reducing power consumption. Specifically:
* **Power-down modes:** What are the most effective power-down modes for the EOS S3, and how can I trigger them effectively based on system activity? Are there any examples of using these modes in conjunction with interrupts?
* **Logic optimization:** Are there specific coding styles or synthesis directives that significantly reduce power consumption in QuickLogic FPGAs? Should I focus on minimizing transitions or reducing the overall gate count?
* **Peripheral management:** I'm using the SPI and I2C peripherals. Are there any power-saving strategies for managing these peripherals when they are not actively in use? Should I completely disable them or use a low-power mode?
* **Memory access:** I'm using internal SRAM. Are there any techniques to minimize power consumption during memory access? Are there recommendations on how to arrange data in memory to improve power efficiency?
* **Debugging Tools:** Which QuickLogic debugging tools are useful in measuring power consumption.
Any insights, code snippets, or pointers to relevant documentation would be greatly appreciated. I'm also interested in hearing about any real-world experiences others have had with optimizing power consumption on QuickLogic FPGAs. Thanks in advance!.
