Aiming at trend of technology combining artificial intelligence and sensor

two kinds of hardware implementation methods of support vector machine（SVM） kernel fuction operation are presented.The two methods both support multiple operations of kernel functions and use serial operation style

which avoid the disadvantage of unflexibility to sample amount and excessive sensitivity of area to sample amount in previous structure.The two methods are compared in multiple perspectives

and advantages and disadvantages are discussed.Experimental result shows that one of them suits the situation of critical area limitation and supporting small amount of kernel functions

while the other one suits the situation of high-speed and supporting more amounts of kernel functions.
