Significant Improvements in the Big Core Regarding the Cortex X3, I had seen someone mention that it is a product of the Sophia team, a newly developed architecture that is different from X1/X2, and I have always been skeptical about it. It seems to be true now. When X2 was released, I thought that with … Read more

Previously, reinforcement learning theory has inspired and enlightened neuroscience: Recently, there has been exciting progress in understanding the mechanisms involved in reward-driven learning. This progress is partly achieved by inputting ideas from the field of reinforcement learning (RL). Most importantly, this input has led to a dopamine-based functional theory grounded in RL. Here, the phase … Read more

Introduction A few years ago, I wrote an OS that ran on STM32 and other Cortex-M series processors. Since I wasn’t familiar with the Cortex-A series processors, I hadn’t ported the OS to them. Later, I learned some knowledge about the ARMv7A instruction set and ported my OS to the ZYNQ7020 chip, which helped me … Read more
