A decade later, she made systematic and creative achievements in the research and design of high-speed computer.
Xia was also responsible for developing the high-speed array processor, which improved the processing speed of regular seismic data in petroleum prospecting by a factor of ten. The operational speed of vector processor designed based on this principle is five times that of other processors then in the country.
