摘要： A system and method for merging a plurality of sorted lists using multiple processors having access to a common memory in which N sorted lists which may exceed the capacity of the common memory are merged in a parallel environment. Sorted lists from a storage device are loaded into common memory and are divided into a number of tasks equal to the number of available processors. The records assigned to each task are separately sorted, and used to form a single sorted list. A multi-processing environment takes advantage of its organization during the creation of the tasks, as well as during the actual sorting of the tasks.

摘要： A display management system for one or more large plasma gas panel displays (11) is organized to split the display management operations between a host processor (20), a system microprocessor (21) and a picoprocessor (27). The picoprocessor (27) is the heart of a common internal bus (31) plasma display adapter (22). The program for the display is downloaded from the host processor (20) to the system microprocessor (21). The microprocessor generates op codes and initializes display parameters. The plasma display adapter provides control for the plasma panel interface, serialization of character generator data, translates display position addresses for absolute cartesian coordinates to panel address, and computes the boundaries of display panel write and erase operations. Interaction between the system microprocessor and the plasma display adapter is minimized by a code list contained in the microprocessor memory and fetched by direct memory access. This code list contains high level commands which the picoprocessor in the adapter decodes and translates into simple commands for the surrounding interface logic.
摘要翻译：组织用于一个或多个大型等离子体气体面板显示器（11）的显示管理系统以在主处理器（20），系统微处理器（21）和微处理器（27）之间分割显示管理操作。微处理器（27）是公共内部总线（31）等离子体显示适配器（22）的心脏。用于显示的程序从主处理器（20）下载到系统微处理器（21）。微处理器生成操作码并初始化显示参数。等离子显示适配器提供对等离子面板接口的控制，字符发生器数据的串行化，将绝对笛卡尔坐标的显示位置地址转换为面板地址，并计算显示面板写入和擦除操作的边界。通过包含在微处理器存储器中并通过直接存储器访问获取的代码列表将系统微处理器和等离子体显示适配器之间的相互作用最小化。该代码列表包含高级命令，适配器中的微处理器解码并转换为周围接口逻辑的简单命令。
