In the era of the Internet of Things, the relentless pursuit of performance, power consumption, and cost in embedded systems has never ceased. At the elexcon 2025 Shenzhen International Electronics Exhibition and Embedded Exhibition held last week, XuanTie officially launched the new generation XuanTie E901 Processor. As a revolutionary upgrade to the classic XuanTie E902 processor in the XuanTie embedded E series, the XuanTie E901 fully leverages the advantages of the latest RISC-V instruction set technology, delivering lower power consumption, higher code density, and more flexible architectural design, meeting the application needs in fields such as the Internet of Things, wearable devices, and industrial control.
Ultra-Simplified, Breaking Hardware Design Limitations
-
Ultra-low power consumption, providing devices with extended standby time Compared to the XuanTie E902 processor, while maintaining the same technical characteristics, the new XuanTie E901 processor achieves a dynamic power consumption optimization of 48%. The XuanTie E901 has optimized the sleep mode, with the deep sleep mode capable of fully meeting the stringent power requirements of wearable devices and smart sensors.
-
Area optimization, drastically reducing chip costs Compared to the XuanTie E902 processor, the new XuanTie E901 processor can achieve at least a 10% to a maximum of 39% area optimization, significantly lowering chip development costs.
-
Increased code density, further reducing chip costs By introducing the latest RISC-V compressed instructions, the XuanTie E901 processor achieves a 6% increase in code density compared to the XuanTie E902, meaning that chips equipped with the new XuanTie E901 processor can perform more functions within the same storage space.
-
Improved energy efficiency ratio, balancing real-time performance and efficiency In addition to the optional single-cycle 32 × 32 multiplier, the new XuanTie E901 processor also adds a hardware divider. Compared to the XuanTie E902 processor, the Dhrystone energy efficiency ratio of the XuanTie E901 can be improved by approximately 48%.
-
Co-processor interface support The XuanTie E901 processor introduces a co-processor interface design, allowing developers to define private instructions for customized instruction extensions, which can seamlessly integrate with the XuanTie toolchain.
