C6678 EMIF16数据传输带宽疑问-1



查阅资料,找到了关于KeyStone器件的一些传输带宽数据,如下所示

查看EMIF16的传输带宽时,产生了如下一些疑问,先上图

问题1:“EMIF Clock is based on SYSCLK7 CorePac Frequence devided by 6 and 2 cycles per period”对这一句的理解是,EMIF的时钟是SYSCLK7引出来的,且是内核时钟的1/6或者1/2,而6678 的Data Manual也是这样描述的“SYSCLK7: 1/6-rate clock for slow peripherals (GPIO, UART, Timer, I2C, SPI, EMIF16, etc.) and sources the SYSCLKOUT output pin. ”且SYSCLK7是CPU/6的频率。试问KeyStone系列器件中哪一款是的EMIF16时钟是CPU/2?

问题2:在计算EMIF16的带宽时,采用了这个公式(EMA_CLK)/(Setup+Strobe+Hold) *16 bit,试问EMA_CLK是什么意思?具体的值是多少?
