Silicon Mobility designs, develops and sells flexible, real-time, safe and open control solutions for the automotive industry.

Silicon Mobility’s products and technologies address the limitations of the system architectures currently used in the automotive industry for safety critical real-time applications in terms of software bottlenecks/performance restrictions specifically with regard to

  • Real-time data processing capabilities and the hard real-time control loop frequencies deriving from,

  • Non deterministic architectures and their implications, in particular their acquisition to actuation processing times variations subject to CPU load on sequential architectures,

  • Software based functional safety with no acceleration and thus slow reaction time to system faults,

  • High power consumption and consequential heat,

  • Software dependencies coming along the usage of proprietary processor core architecture.

In a context where those issues are currently exacerbated by heavy increases in the demand for processing capacity particularly in the ADAS/Autonomous Driving and Powertrain Electrification areas as well as the resulting strong push for centralizing the control units in the car.

By processing locally and in parallel the events controlling e-motors and batteries, the Silicon Mobility technology removes the software bottlenecks limiting the frequency of the control loops, multiplying their performances by a factor of 20 to 40, and reducing their power consumption by a factor of 180.

Silicon Mobility technology is hardware based, programmable logic and timing predictable resulting in the acceleration of the safety mechanisms. In particular, the reaction time to faults, from detection to containment or correction, is reduced by a minimum of 1000 times.

The technology is embedded within a family of processing unit invented by Silicon Mobility, OLEA® FPCU (Field Programmable Control Unit), a flexible electronic circuit specialized to compute, take decision and act fast, in all safety, and deterministically.

OLEA® can therefore improve the efficiency and the performance of electric motors and batteries, reduce their size, weight, heat and cost, and increase the battery range and charging speed by a substantial margin.

Together with these car level benefits, OEMs can enjoy numerous economic advantages through the implementation of OLEA, in particular savings, significant, at BOM level and a large footprint and heat reduction that leads directly to the increase of quality and durability.

Furthermore, the software and hardware programmability offered by the technology radically reduces the OEMs development cycles and eases calibration, maintenance and re-usability. As a highly-appreciated implication, the control of e-motors and batteries becomes therefore not only updatable and upgradable during development time but also during product life.

Finally, Silicon Mobility’s technology is open as it uses widely available and licensable processor core technology (eg ARM®) and comes with a unique design flow, seamless and homogeneous, and a full software stack that enable OEMs to accelerate time-to-market, reduce development cost and take back value by accelerating the adoption and the implementation of a “Built-to-Print” business model.

Beyond Powertrain Electrification Silicon Mobility’s road map encompasses its deployment into the broader Electrification (Steer by wire, EPS, braking, etc) and the CPU centralization in the car area, in particular with regard to ADAS data fusion and domain control.
