Chinese Scientists De­velop New Type of Brain-In­spired Chip

Chinese scientists have suc­cess­fully de­vel­oped a ground-break­ing elec­tronic chip and incorporat­ed it into a rid­er­less au­ton­o­mous bi­cy­cle. The bi­cy­cle can de­tect and track tar­gets, avoid obstacles, self-bal­ance, un­der­stand voice com­mands and even make in­de­pen­dent de­ci­sions as a re­sult of the chip’s si­mul­ta­ne­ous pro­cess­ing of versatile al­go­rithms and mod­els. The re­search achieve­ment, con­ducted by Shi Lup­ing and his col­leagues at the Cen­tre for Brain In­spired Com­put­ing Re­search of Ts­inghua Univer­sity, was pub­lished as the cover story of Na­ture

Mag­a­zine on Thurs­day. Ac­cord­ing to the ar­ti­cle, there are two main ap­proaches to de­vel­op­ing ar­ti­fi­cial gen­eral in­tel­li­gence. One is rooted in neu­ro­science and at­tempts to con­struct cir­cuits that closely mimic the brain.

The other is grounded in com­puter sci­ence and uses com­put­ers to ex­e­cute ma­chine-learn­ing al­go­rithms.

Shi’s Tian­jic chip can in­te­grate the two ap­proaches into one hy­brid plat­form, which en­ables it to ac­com­mo­date both ma­chine-learn­ing al­go­rithms and brain-in­spired cir­cuits.

The first gen­er­a­tion of the Tian­jic chip was de­vel­oped in 2015, fol­lowed by the sec­ond gen­er­a­tion in 2017. Af­ter con­tin­u­ous im­prove­ment, the cur­rent sec­ond-gen­er­a­tion Tian­jic chip fea­tures even higher per­for­mance with much lower power con­sump­tion. “Com­pared with sim­i­lar chips in the mar­ket, our chip’s den­sity is 20 per cent higher, at least 10 times faster and its band­width has been in­creased by at least 100 times,” Shi said.

“The Tian­jic chip aims to pro­vide a more ef­fi­cient, fast and flex­i­ble com­put­ing plat­form for the re­search of ar­ti­fi­cial gen­eral in­tel­li­gence, as well as the devel­op­ment of var­i­ous ap­pli­ca­tions,” Shi said.
