Figure 1. PCI-X Core Function
Description
PLDAs' PCI-X core provides programmable logic device (PLD) and ASIC designers with a versatile and integrated solution to interface any user application or system to 32- or 64-bit PCI-X peripheral devices. Moreover, the PCI-X core is fully programmable and customizable, easily adaptable to run in any PCI-X environment, and provides features that can be enabled or disabled to suit specific needs.
As shown in Figure 1, PLDAs' PCI-X core is built around target and master state machines that control all operations to ensure coherence and synchronization with PCI-X bus operation. Data transfer is operated by a 32- or 64-bit bidirectional registered datapath.
Although the PCI-X core primarily targets the add-on card market (including PLDAs' own development and prototyping boards), it can be beneficial in virtually all types of applications, including data acquisition, imaging, industrial controls, and communication system designs.
