In December 2016, Vivienne Sze, Yu-Hsin Chen, and others (authors of Eyeriss) published a good review article titled “Hardware for Machine Learning: Challenges and Opportunities” on arXiv. Here, I would like to discuss my understanding of the “challenges” and “opportunities” in conjunction with this article [8] and the ISSCC2017 paper [1-7]. First, this discussion mainly … Read more
Recently, a friend asked: What is the relationship between ARM9 and STM32? If we turn back time 10 years, ARM9 and S3C2410 were quite popular, but the “new era” ARM processors like STM32 also emerged. ARM9 is an early ARM processor, while STM32 is a more popular processor in recent years. ARM Naming Rules The … Read more
As we all know, embedded systems have advantages such as small size, high reliability, strong performance, and low power consumption, gradually occupying a dominant position in modern medical devices, primarily using ARM processors. With the continuous improvement in functionality and performance requirements for medical devices, the industry’s demands for processors have also evolved from traditional … Read more
