GTE
GTE Corporation, formerly General Telephone & Electric Corporation (1955-1982) was the largest independent telephone company in the United States during the days of the Bell System. The company operated from 1926, with roots tracing further back than that, until 2000, when it merged with Bell Atlantic; the combined company took the name Verizon.
Originally founded as Associated Telephone Utilities, it went bankrupt in 1933 during the Great Depression, and reorganized as General Telephone in 1934. In 1991, it acquired the third largest independent, Continental Telephone (ConTel). They also owned Automatic Electric, a telephone equipment supplier similar in many ways to Western Electric, and Sylvania Lighting, the only non-communications-oriented company under GTE ownership. GTE provided local telephone service to a large number of areas of the U.S. through operating companies, much as American Telephone & Telegraph provided local telephone service through its 22 Bell Operating Companies.
Generic Tile Engine
GTE (Generic Tile Engine) is a 2D tile engine developed for the Apple IIGS personal computer and written in 65816 assembly language.
History
The underlying technology was developed for a recreational port of Super Mario Bros for the Apple IIGS platform. At this point the engine only supported single-layer backgrounds, a single non-standard tile size and limited sprite support. After the release of the unfinished SMB GS, the core graphics engine was modularized and released as a GS/OS Tool Set.
Features
GTE provides graphical capabilities that lie roughly between the third and fourth generation of video game consoles. The technical capabilities of the engine are contrasted with the NES and SNES consoles, which share the same CPU family as the Apple IIGS
Implementation
The memory bandwidth of the Apple IIGS is 1 MiB/s, which is too slow to update the 32 KiB graphics memory at a full 60 frames per second. In fact, the theoretical maximum frame rate for full-screen animation is 31.25 frames per second. Thus, GTE focuses on achieving a reasonable frame rate given the limitations of the hardware.
