Table 7 lists the base and optional powerpc floating - point instruction set 表7列出了基本的和可選的powerpc浮點(diǎn)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,嵌入式微處理器實(shí)現(xiàn)時(shí)經(jīng)常不提供對(duì)浮點(diǎn)指令集的直接硬件支持,或者只是提供一個(gè)附加浮點(diǎn)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 該系統(tǒng)中采用的ip核主要包括自主研發(fā)的兼容intelx86定點(diǎn)指令集的定點(diǎn)微處理器核和兼容intelx86浮點(diǎn)指令集的浮點(diǎn)微處理器核,還包括片上rom核、連接soc外部的接口等。
