Abstract: This disclosure relates to an information processing system employing plural processors which system is provided with a free field storage array to accommodate operands and data segments of any size and format. Each of the respective memory storage units is, in fact, structure oriented. However, pairs of such storage units are provided with isolation units having the capability of extracting and inserting fields of information independent of the memory structure. During a fetching operation, the isolation unit is adapted to fetch two contiguous parallel words and a shifting network or barrel switch is provided to position the desired field for transfer to the requesting device. During a store operation, the shifting network or barrel switch is employed to position incoming data into the proper bit location of the memory. The selected field is determined by the starting bit and the length field information provided by the memory control word and also by the type of operation requested. Each of the requesting devices is provided with its own interface unit that contains logic to construct a memory control word for each memory module involved in a fetch or store operation. In this manner, the entire array of memory units will appear to each of the requesting devices as being free field or without structure.

Abstract translation: 本公开涉及一种采用多个处理器的信息处理系统，该系统具有自由场存储阵列以适应任何大小和格式的操作数和数据段。 实际上，各个存储器单元中的每一个实际上都是结构化的。 然而，这样的存储单元的对被提供有具有提取和插入与存储器结构无关的信息字段的能力的隔离单元。 在提取操作期间，隔离单元适于获取两个连续的并行字，并且提供移动网络或桶开关以将所需字段定位以传送到请求设备。 在存储操作期间，使用移动网络或桶形开关将输入数据定位到存储器的适当位位置。 所选择的字段由存储器控制字提供的起始位和长度字段信息以及所请求的操作类型确定。 每个请求设备被提供有其自己的接口单元，其包含逻辑以构建在获取或存储操作中涉及的每个存储器模块的存储器控​​制字。 以这种方式，整个存储器单元阵列将显示给每个请求设备，作为自由场或没有结构。
