Kazunori Masuyama, an accomplished inventor based in Kanazawa, Japan, has made significant contributions to the field of technology with a remarkable portfolio of 15 patents. His work predominantly revolves around data transfer systems and memory management, particularly in applications involving central processing units (CPUs).

Latest Patents

Masuyama's latest patents focus on advanced functionalities in direct memory access (DMA) controllers and PCI-Express communication systems. The DMA controller patent outlines a method where a transfer control unit transmits messages and data to a discretionary node through a serial bus or switch upon receiving a request from a CPU firmware. Notably, this system employs a descriptor that includes a flag indicating whether a response from the data transmission destination is necessary. In scenarios where the flag is set to ON, the control unit notifies the firmware of a simulated completion, optimizing the data transfer process.

In his PCI-Express communications system patent, Masuyama introduces a unique node ID to each node, ensuring that the response packet is conveyed correctly even after a bus ID or device ID change within the PCI-Express switch. This innovation also includes mechanisms to maintain the correct order of data packets, utilizing a sequence code within the packet’s address field to manage the flow of data accurately.
