Page-oriented optical memories combine high capacity with massive data-transfer rates and could provide the next generation of secondary storage systems. Several technological barriers need to be overcome before these memories become commercial products. One is the need for efficient interfaces to electronic computers. To assist in the analysis of all issues pertaining to such an interface, we have developed the optical storage interactive simulator (oasis), an interactive software tool. oasis can simulate data-encoding schemes, noise sources present in a particular memory system, and data-recovery mechanisms. Bit-error rates and other useful statistics can also be measured. The user has the option of studying the effects of individual error sources to the system output or of applying several of them in any order dictated by the system architecture. This multifaceted analysis will assist the user in evaluating the effectiveness of a particular error-correcting code and choosing the right one for the system.
面向页面的光学存储器将高容量与海量数据传输速率相结合，有望提供下一代二级存储系统。在这些存储器成为商业产品之前，需要克服几个技术障碍。其中之一是需要与电子计算机建立高效接口。为了帮助分析与这种接口相关的所有问题，我们开发了光学存储交互式模拟器（OASIS），这是一种交互式软件工具。OASIS可以模拟数据编码方案、特定存储系统中存在的噪声源以及数据恢复机制。还可以测量误码率和其他有用的统计数据。用户可以选择研究单个错误源对系统输出的影响，或者按照系统架构规定的任何顺序应用其中几个错误源。这种多方面的分析将帮助用户评估特定纠错码的有效性，并为系统选择合适的纠错码。
