Table 7 lists the base and optional powerpc floating - point instruction set 表7列出了基本的和可选的powerpc浮点指令集。
Note that embedded microprocessors are frequently implemented without direct hardware support for the powerpc floating - point instruction set , or only provide an interface to attach floating - point hardware 注意,嵌入式微处理器实现时经常不提供对浮点指令集的直接硬件支持,或者只是提供一个附加浮点硬件的接口。
The ip cores used in this system include an integer processor core compatible with the intelx86 integer instruction set and an floating - point processor core compatible with the intelx86 floating - point instruction set , which are developed by ourselves 该系统中采用的ip核主要包括自主研发的兼容intelx86定点指令集的定点微处理器核和兼容intelx86浮点指令集的浮点微处理器核,还包括片上rom核、连接soc外部的接口等。
