Title: Keizo Sumida: Innovator in Processor Technology

Introduction

Keizo Sumida is a notable inventor based in Hirakata, Japan. He has made significant contributions to the field of processor technology, holding a total of 11 patents. His work focuses on enhancing the efficiency and speed of data processing.

Latest Patents

One of his latest patents involves a processor designed to execute a rounding process that includes positive conversion and saturated calculation processing. This innovative processor can convert coded data into uncoded data and perform saturation calculation processing at high speed. When the positive conversion saturation calculation instruction 'MCSST D' is decoded, the sum-product result register outputs its held value to the designated path. The comparator then compares this value with the coded 32-bit integer '0x0000_00FF'. Additionally, the polarity judging unit determines whether the eighth bit of the held value is "ON". The multiplexer subsequently outputs one of three values: the maximum value '0x0000_00FF', the zero value '0x0000_0000', or the held value of the sum-product result register to the data bus.

Career Highlights

Throughout his career, Keizo Sumida has worked with prominent companies such as Matsushita Electric Industrial Co., Ltd. and Panasonic Corporation. His experience in these organizations has allowed him to develop and refine his innovative ideas in processor technology.

Collaborations

Keizo has collaborated with notable coworkers, including Toru Morikawa and Nobuo Higaki. Their combined expertise has contributed to advancements in the field of technology.

Conclusion

Keizo Sumida's contributions to processor technology and his impressive portfolio of patents highlight his role as a significant innovator in the industry. His work continues to influence the development of efficient data processing systems.
