Abstract: An embodiment of the disclosure provides a voice communication method, a calling terminal, a called terminal and a system, the voice communication method includes: establishing, by a calling terminal, a data communication connection between a called terminal and the calling terminal; obtaining a calling terminal international mobile subscriber identity (IMSI), a called terminal IMSI, a first random number for encryption and decryption, and generating a first encryption key; encrypting voice signals according to the first encryption key by using a preset encryption algorithm and obtaining first encrypted voice signals; sending the first encrypted voice signals to the called terminal. The first encryption key is generated according to the calling terminal IMSI, the called terminal IMSI, and the voice signals are encrypted by using the preset encryption algorithm, thus an encryption process is highly targeted and highly confidential, and security of voice services is improved.

Abstract: Systems and methods for a hybrid system-on-chip usable for predicting performance and power requirements of a host server include a big cores module, including central processing units, for receiving and pre-processing performance and power metrics data of the host server and to allocate computing resources, a small cores module, including massively parallel processing units, for mapping each instance associated with host server in the performance and power metrics data to a corresponding massively parallel processing unit based on the allocated computing resources for a per-instance metrics calculation, and an artificial intelligence (AI) accelerator for calculating performance and power prediction results based on the per-instant calculations from the small cores module.
