The paper proposes a solution to digitize the angle information of the two speed resolvers based on tangent algorithm. This solution is simple than the tracking types in common use. The principle is analysed and the configuration of software and hardware is presented. To avoid overflow and improve precision, sampling at the signal peak and two tables are adopted. The experiments show that the solution...
Comparing with the passion for verification technical innovations, the practical verification experiences especially the bug reports and analyses rarely appear in public research. It is very important to analyze the practical bug reports for feedback on the future verification. Thanks to the sufficient design scale of our microprocessor and efficient verification environment we developed, we are able...
The verification of processor cores is very important for SOC design. In this paper we present a verification methodology that extends and enhances the traditional verification methodology to address the configurablility, debugability and other characteristics of processor cores. The proposed methodology has been taken into practice for the verification of a 32-bit embedded processor core - Godson-1...
