SAN JOSE, CA -- Cadence Design Systems, Inc. announces that Espressif Systems has utilized the Cadence® Tensilica® Xtensa® processor in its ESP8089 and ESP8266 WiFi chips that are optimized for Internet of Things (IoT) applications. The Xtensa processor, customized by Espressif to achieve the best power, performance and area results, is used both as a digital signal processor and control processor with a real-time operating system (RTOS) that runs Espressif's WiFi and TCP/IP stacks and other application software.
"With a rapid customization of the 32-bit ultra-low power Xtensa processor, we were able to combine the control and DSP functions into one very efficient core, conserving power and area for these very space-constrained designs," said Teo Swee Ann, CEO of Espressif Systems. "We also utilized ultra-low voltage technology, dynamic voltage and frequency scaling, and an advanced power-control algorithm to achieve standby power consumption of less than 1.0mW and unrivaled 30uA RTC deep-sleep current consumption."
The advantages of the Tensilica Xtensa processor include:
•The capability to integrate both performance-intensive digital signal processing (DSP) and embedded control processing functions in a single core
•The patented automated Xtensa Processor Generator, which allows designers to create differentiated features with the lowest possible power/area
