This paper presents the architectural specification of the , a critical component within the Oberon system's display subsystem. While the original Oberon system utilized a frame-buffer approach, modern implementations requiring hardware acceleration and memory efficiency necessitate a "Tiler" architecture. This document explores the "Link" mechanism—the data structure and pointer logic that binds logical display objects to physical tile generation. We demonstrate how this mechanism minimizes memory bandwidth, supports infinite canvas abstraction, and maintains the Oberon philosophy of modularity and type-safety.
