    Abstract: A processor-based system (22) may include a main processor (24) and a coprocessor (26). The coprocessor (26) handles instructions that include opcodes specifying a data processing operation to be performed by the coprocessor (26) and a coprocessor identification field for identifying a target coprocessor for coprocessor instructions. Two bits indicate one of four data sizes including a byte (8 bits), a half word (16 bits), a word (32 bits), and a double word (64 bits). Two other bits indicate a saturation type.

    Abstract translation: 基于处理器的系统(22)可以包括主处理器(24)和协处理器(26)。 协处理器(26)处理包括指定要由协处理器(26)执行的数据处理操作的操作码的指令和用于识别用于协处理器指令的目标协处理器的协处理器识别字段。 两位表示四个数据大小之一,包括一个字节(8位),一个半字(16位),一个字(32位)和一个双字(64位)。 另外两个位表示饱和类型。
