||IEEE ISSCC (Institute of Electrical and Electronics Engineers - International Solid
State Circuit Conference) 1981. A speaker of Advanced Circuit
Applications session, "A Single-chip
Graphics Display Controller". NEC (Nippon Electric Corporation) µPD7220
GDC (Graphics Display Controller), which is one of my masterpieces, was introduced.
This product was developed by NEC under technology exchange contract
signed between Intel and NEC in 1979. Intel became one of second sourcers.
||Various presentation related to computer
graphics has been done by me at multiple seminars. The title of this
seminar is "Digital Image Processing Technology & the Realistic Application Technique
8/26/23". I took
part in as an author and a lecturer of Graphics & Image Processing
Processor LSI session.

|Full functional description of
(World's first flat panel / CRT VGA controller developed in 1988) &
(Enhanced flat panel / CRT VGA controller developed in 1989) is attached. 82C457Updated on
(Color flat panel / CRT VGA controllerUpdated on
9/25/22) was developed with
color feature in 1990 as well. These products were exhibited at
Comdex Fall every year and obtained superb reputations. They support
various kind of LCD (Liquid Crystal Device), Plasma, and EL (Electro-Luminescence) flat panel interfaces.
Arun Johary, application engineer of Chips and Technologies, and I
coauthored thesis concerning 82C455
(2,078KB) published on Electronic Design magazine.
||Excerpt of the functional specification of
MPEG audio decoder (HD814102
: Hitachi version) is attached. The original ASCII version product name is DA7190.
The original product was developed by GCA (Graphics Communications
America), one of world-wide subsidiaries of ASCII Corporation located in
Chicago, Illinois. Due to financial constraint, ASCII terminated GCA and
inherited the VLSI development at San Jose, CA. The two products above
were developed and manufactured in mass production. The product was one
of three working MPEG decoder LSIs in the world in early 1993.
