CoolBio Ultra-low Power Biomedical Signal Processor

Imec, Holst Centre and NXP partnered on the CoolBio ultra-low power biomedical signal processor. The CoolBio biomedical processor is optimized between performance and power consumption. Medical device companies, semiconductor manufacturers and fabless design houses can evaluate the CoolBio or develop their own bioprocessor by joining imec’s research program on ultra-low power processing for body area networks, which is part of the HUMAN++ program.

CoolBio ultra-low power biomedical signal processor - imec, Holst Centre, NXPCoolBio Biomedical Processor Features

  • C-programmable chip
  • Coltage and performance scalable
  • Based on the NXP low power CoolFlux DSP baseband core
  • Meets the requirements of future wearable biomedical sensor systems
  • Supports a frequency range of 1MHz up to 100MHz with an operating voltage from 0.4 to 1.2V
  • Reduces power of the wireless BAN sensor nodes
  • Processing and compressing data locally on the BAN node
  • Limits power hungry transmission of data over the wireless link, while adding motion artifact reduction and smart diagnosis
  • Architecture and circuitry operate at near-threshold voltage (0.4V) at low operating frequencies
  • Extreme separation into multiple voltage power, clock and memory domains were implemented
  • High energy efficiency from standby to 100 MHz performance
  • Consumes only 13pJ/cycle when running a complex ECG (electrocardiogram) algorithm at 1MHz and 0.4V operating voltage
