摘要： Fortran 语言在科学与工程计算领域具有广泛应用。然而,通用数字信号处理器(General-Purpose Digital Signal Processor,GPDSP)目前主要使用C语言或汇编语言进行编程,尚不支持 Fortran 语言。针对这一现状,面向 CPU-DSP 异构处理器的 Fortran 编译器实现技术,基于LLVM Flang 编译器框架设计并实现了 Fortran 编译器原型 mtFortran,完成了 Flang 前端移植,并重点解决了 Fortran 程序在异构架构上的编译和运行支持,包括加载执行、语法支持、内建函数实现及输入输出(I/O)系统适配问题。实验结果表明,该 Fortran 编译器成功支持 Fortran 语言商用测试集 U_F90_TS_LITE 中 GUIDE F90 测试集的语法特性,在 176 个测试程序中运行时库已完全支持的测试程序(102 道)全部通过异构编译与加载执行验证,主要类别内建函数的实现率达 79.38%,并可支持典型高性能计算程序的运行(如 NPB-EP 测试程序),实现了 Fortran 程序在 CPU-DSP 异构处理器架构上的基础运行能力,为后续完善标准支持、性能优化及并行化扩展奠定了基础。
