A new coupled shear mode surface acoustic wave device is realized!​

It was learned from the University of Science and Technology of China on February 26 that the research team of Professor Zuo Chengjie from the School of Microelectronics of the school proposed and implemented a new type of coupled shear mode surface acoustic wave device (X-SAW for short) for the first time in the world. By utilizing the mutual coupling of shear piezoelectric coefficients in two different directions, an electromechanical coupling coefficient of up to 34% and a quality factor (Q value) of up to 650 are achieved at a high frequency of 5GHz. The relevant results were published on February 23 in the electronic device field journal "IEEE Electronic Devices Communications".

Microelectronics has made important progress in digital-analog mixed storage and computing integrated chips​


A team of Academician Liu Ming of the Institute of Microelectronics, Chinese Academy of Sciences developed an integrated digital-analog hybrid storage and computing macro chip based on outer product operation, designed a digital-analog hybrid floating-point SRAM in-memory computing scheme, and proposed an analog and digital The hybrid method of storage macro combines the advantages of using an analog storage scheme for efficient in-array bit multiplication and a digital storage scheme for efficient multi-bit shift accumulation outside the array, achieving overall high energy efficiency and area efficiency. Through the residual digital-to-analog converter architecture, the required resolution of the digital-to-analog converter is only the logarithm of the input bit precision, achieving high throughput and low overhead. Through a floating-point/fixed-point block architecture based on the mathematical principles of matrix outer product calculations, matrix-matrix-vector calculations can be completed through accumulator elements. Compared with previous digital storage and calculation solutions using large fan-in, multi-stage adder trees based on the matrix inner product principle, the throughput rate is higher. The architecture also supports fine-grained unstructured activation sparsity to further improve overall energy efficiency.

This storage and computing integrated macro chip is tape-out under the 28nm CMOS process and can support BF16 floating-point precision operations and INT8 fixed-point precision operations. The peak energy efficiency of BF16 floating-point matrix-matrix-vector calculation reaches 72.12TFLOP/W, and INT8 fixed-point matrix-matrix- The peak energy efficiency of vector computing reaches 111.17TFLOP/W. This research result provides new ideas for storage and computing integrated architecture chips using digital-analog hybrid solutions.
