PCI Express Compiler User Guide
Figure 1–1. Example PCI Express System
Optimized for Altera devices, the PCI Express Compiler supports all
memory, I/O, configuration, and message transactions. The MegaCore
functions have a highly optimized application interface to achieve
maximum effective throughput. Because the Compiler is
parameterizable, you can customize them to meet design requirements
by using the MegaWizard interface in the Quartus
example, the MegaCore functions can support up to 4 virtual channels for
x1 or x4 configurations, or up to 2 channels for x8 configurations. You also
can customize the payload size, buffer sizes, and configuration space
(base address registers support and other registers). Additionally, the PCI
Express Compiler supports end-to-end cyclic redundancy code (ECRC)
and advanced error reporting for x1, x4, and x8 configurations.
The PCI Express MegaCore functions also include debug features that
allow observation and control of the MegaCore functions. These
additional inputs and outputs help with faster debugging of system-level
problems.
