Abstract: A processor includes a scalar processor core and a vector coprocessor core coupled to the scalar processor core. The scalar processor core is configured to retrieve an instruction stream from program storage, and pass vector instructions in the instruction stream to the vector coprocessor core. The vector coprocessor core includes a register file, a plurality of execution units, and a table lookup unit. The register file includes a plurality of registers. The execution units are arranged in parallel to process a plurality of data values. The execution units are coupled to the register file. The table lookup unit is coupled to the register file in parallel with the execution units. The table lookup unit is configured to retrieve table values from one or more lookup tables stored in memory by executing table lookup vector instructions in a table lookup loop.

Abstract: A computer system includes a processor and program storage coupled to the processor. The program storage stores a software instruction translator that, when executed by the processor, is configured to receive source code and translate the source code to a low-level language. The source code is restricted to a subset of a high-level language and the low-level language is a specialized instruction set. Each statement of the subset of the high-level language directly maps to an instruction of the low-level language.

Abstract translation: 计算机系统包括耦合到处理器的处理器和程序存储器。 程序存储器存储软件指令转换器，当由处理器执行时，其被配置为接收源代码并将源代码转换为低级语言。 源代码限于高级语言的子集，低级语言是专门的指令集。 高级语言的子集的每个陈述直接映射到低级语言的指令。
