Book Organization
The book is organized into 2 parts.
In Part I: Math and Logic Design
Chapters 1 to 10
In the 1st part, the author introduces new concepts for implementing efficient logic circuits and for doing computations with binary numbers. He shows several examples where his techniques produce better designs with lower gate count and lower cost.
A new type of numbers, the averaged numbers, is introduced. Several examples and applications are presented where averaged numbers provide better solutions than rounded numbers. The examples include: Addition, Multiplication, Divisions and functions like exp(x), log(x), ln (x), lg2(x), sin(x) and cos(x).
In Part II: CIG History.
Chapters 11 to 14
In the 2nd part, the author describes his experience designing the fastest real-time Computer Image Generator (CIG) systems at Link Flight Simulation, in Sunnyvale, CA. The Link DIG-1 was the first real-time CIG from Link and was delivered to Houston in 1976. Four SMS DIG-1 were delivered to NASA for the Shuttle Mission Simulator (SMS) in Houston, TX, by 1977. There were 2 versions of the DIG: DIG-1 and DIG-2. A total of 70 DIGs were sold. The DIG was used in several simulator/trainer programs for the Air Force (F-111 Fighter, B-52 Bomber, F117 Fighter-Bomber) and Army helicopters (AH-64 Apache, AH-1 Cobra, CH-47 Chinook and UH-60 Black Hawk).
There is also a comparison between the real-time Link DIG and other super-computers.
The 1st Cray-1 Super-Computer was announced in 1976. The same year, 1st SMS DIG-1 was shipped to Houston. The non-real time Cray-1 is compared with the real-time DIG-1.
Five years later, the CT-5 from E&S was announced in 1981. The CT-5 and the DIG-1 have similar performances, although the DIG-1 was produced 5 years earlier.
