A programmable digital engine for RF/analog on-/off-line calibration and Built-in Self-Test (BIST) enables a new level of robustness and portability for mixed signal SoCs. The drop-in IP-block is based on a dedicated CPU with data path and instruction set extensions optimized for the compute intensive RF calibration algorithms. The concept is demonstrated with an implementation in a 32nm SoC test chip where the 0.63mm 2 engine has been fully integrated with a WiFi radio and has been used to measure and calibrate its inherent non-idealities and to evaluate its performance.

Intel Labs is a research arm at Intel focused on delivering innovations to fuel Intel's growth and technology leadership. Intel Labs Mexico, one of the research groups of Intel Labs globally, has been leading research and technology development in Mexico and Latin America since its creation in 2005.
