| ＳＩＭＣ（ＳＩＭＤＣ）是通过对Ｃ语言进行语法扩展（未进行语义扩展）得到的支持ＳＩＭＤ（ｓｉｎｇｌｅｉｎｓｔｒｕｃｔｉｏｎｍｕｌｔｉｐｌｅｄａｔａ）并行程序设计的并行语言．ＳＩＭＣ可方便地描述ＳＩＭＤ并行算法，具有ＳＩＭＤ计算机系统结构定义能力，可支持多种系统结构上的并行算法研究．ＳＩＭＣ语言的模拟执行系统已在单机上实现，并作为作者研究开发的ＳＩＭＤ计算机程序设计及性能评价模拟环境的并行程序设计语言，用于ＳＩＭＤ计算机算法及结构的性能评价. |

| Abstract: |
| IMC (SIMD C) is a SIMD(single instruction multiple data) parallel programming language extended to the syntax of usual C language. SIMC can be easy to program SIMD algorithms. Moreover, it can be used to study SIMD algorithms on differentkinds of SIMD architecture which is defined in SIMC. The simulation environment ofSIMC has been implemented on a sequential computer. This environment can be used toevaluate the performance of SIMD s algorithms and architecture. |
