Recent years, the deep learning algorithm has been widely deployed from cloud servers to terminal units. And researchers proposed various neural network accelerators and software development environments. In this article, we have reviewed the representative neural network accelerators. As an entirety, the corresponding software stack must consider the hardware architecture of the specific accelerator to enhance the end-to-end performance. And we summarize the programming environments of neural network accelerators and optimizations in software stack. Finally, we comment the future trend of neural network accelerator and programming environments.

For enhancing the emission intensity and broadening the excitation region of Ba3Eu(PO4)3(BEP), Sm3+is doped as sensitizer in this paper. BEP:Sm3+can produce an obvious red emission at near ultraviolet (n-UV) radiation. An effective energy transfer from Sm3+to Eu3+is proved. The commission international de I’Eclairage (CIE) chromaticity coordinates of BEP:Sm3+locate at red region. When the environment temperature is 150 °C, the emission intensity of BEP:0.10Sm3+is decreased to 76% of the initial one at room temperature, and the activation energy is calculated to be 0.164 eV, which can prove the good thermal stability of BEP:Sm3+. The results indicate that BEP:Sm3+may have potential applications in white light emitting diodes (LEDs).
