新的IEEE标准-非活动撤销。 规定了可扩展相干接口（SCI）系统中异构多处理器之间交换整数、位域和浮点数据的格式。定义的数据格式还可用于在其他总线标准上的多处理器之间共享数据，这些总线标准支持IEEE Std 1212-1991 CSR体系结构定义的读、写和锁事务集。其目的是在分布式计算环境中支持异构工作站之间的高效数据传输。（不再得到IEEE的认可）

New IEEE Standard - Inactive-Withdrawn. Formats for interchanging integer, bit-field, and floating point data between heterogeneous multiprocessors in a Scalable Coherent Interface (SCI) system are specified. The defined data formats can also be used to share data among multiprocessors on other bus standards that support the read, write, and lock transaction set defined by IEEE Std 1212-1991 CSR Architecture. The intent is to support efficient data transfers among heterogeneous workstations within a distributed computing environment. (No longer endorsed by the IEEE)
