Title: Akio Makimoto: Innovator in Packet Switching Technology

Introduction

Akio Makimoto is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of packet switching technology, holding a total of 4 patents. His work has been instrumental in advancing communication systems and improving data transmission efficiency.

Latest Patents

One of his latest patents is the "Shared buffer type variable length packet switch." This invention features a structure that allows for writing variable length packets received from input lines into a shared buffer memory on a fixed length data block unit basis. The buffer controller forms an input queue for each input line and links a linked address list for the input queue to one or more output queues corresponding to packet destination output lines when the last data block of a variable length packet is registered.

Another notable patent is the "ATM switch," which provides a high-throughput large-capacity ATM switch. This invention addresses the variation in memory access time and data output delay time that occurs when using DRAM as a cell buffer. The ATM switch comprises a first memory using DRAM for storing cells and a second memory using SRAM for switching and temporarily storing cells before transferring them to the first memory. The controller generates write/read address and timing signals for both memories, ensuring efficient data handling.
