I’ve recently returned from a trip to China where I’ve attended the two Imagination Summits organized in Beijing and Shanghai, respectively. Alongside a series of exciting presentations from my colleagues as well many of our ecosystem partners, I also enjoyed seeing several demonstrations and prototypes of next-generation devices using Imagination IP in addition to many real-life products using our technologies.
One Imagination-powered demo I’d like to highlight today comes from Standing Egg and relates to a previous announcement we made earlier this year.
Standing Egg is a Korean fabless start-up that has integrated our MIPS M5100 CPU inside a low power chip designed for sensor fusion. A team of engineers representing the company was present at our summit showcasing two sensor fusion demos running on a compact Xilinx Artix-7 FPGA board.
In addition to the MIPS M-class CPU, the FPGA board also included a Standing Egg SGA100 accelerometer, a gyroscope and magnetometer.
The first demo consisted of a 6-axis IMU (Inertial Measurement Unit) running a filter algorithm that fuses the data from the SGA100 accelerometer and the gyroscope; this provides an efficient computational recursive method to estimate the state of a process at a given time and obtain feedback from the sensor measurements.
After performing calibration and applying another low pass filter to the gyroscope and accelerometer signals (IMU configuration), the resulting signal is used to obtain a smooth measure of rotation in 3D space.
Substituting a real gyroscope inside IoT devices with a software-based implementation can eliminate the high power consumption and increased costs commonly associated with hardware gyroscopes.
