CA57中所有Core共享一个GIC CPU interface?

hi, experts:

CA57 MPCore TRM中:

Page 1-7 :

Note:

All the processors share an integrated L2  cache and GIC CPU interface.

根据Page 2-2 CA57's block diagram:

每一个Core,都有自己的GIC CPU Interface.

因此,CA57 MPCore中:应该是每一个Core都有自己的GIC CPU Interface,而非共享一个?

best wishes,

  • GIC CPU interface的定义是指一组线,参考page A-6的signal,例如nIRQ[N:0],

    N 代表core数量减一。

    所以“All the processors share an integrated L2  cache and GIC CPU interface.” 是正确的。

    Page2-2意思是每个core都会有独立的中断线。
