Notes:
1. SysACE_MPD is formed in the IOB from SysACE_MPD_I, SysACE_MPD_0, and SysACE_MPD_T.
2. SysACE_IRQ should be connected to the interrupt input of the processor.
3. SysACE_Clk should be connected to a global clock buffer by the user.

PLB Interface Module
PLB Interface Module provides an interface between XPS System ACE Interface Controller and the
PLB. The PLB Interface Module implements the basic functionality of a PLB slave and does the
necessary protocol and timing translation between the PLB and the IPIC interface. PLB Interface
Module supports only single beat transactions.
System ACE Interface Controller
The System ACE interface controller contains a controller state machine and logic to synchronize
signals across the SPLB_Clk and SysACE_Clk domains as shown in Figure 2.
