The reference design consists of the following components: Base and Limit Registers for Root Ports. Are there any compiled versions of the drivers that work on current OSes? The table shows the average throughput with the following parameters:. Please use the link below to request access to the lounge.

The following figure highlights this component.

The DMA module also includes a performance counter. The soft IP implementation is available only as an Endpoint.

This number is system dependent. This reference design is available in many different configurations as shown in the following table. The maximum possible throughput is calculated as follows: Our simple reference driver allows you to read and write registers.

Or, the pcid must issue enough non-posted header credits to cover this delay.

This strategy maintains a high throughput. Enable byte parity ports on Avalon-ST interface. Thanks for letting me know.

Good luck in your search for Windows code – I will be eager to hear the response on that as I also have a need to compile for a different version of Windows Windows The on position points away from the PCIe slot. The outstanding requests are limited by the number of header tags and the maximum read request alterw.


PCI Express High Performance Reference Design

The desired performance for received completions and requests is set to Maximum. Please use the link below to request access to the lounge. The following example illustrates this point. PCI Express uses flow control. This table specifies the total number of descriptors and the address of the first descriptor pcoe. FPGA source code as a starting point for a user’s own design.

Open Source Real Time Ethernet on Altera PCIe

Is the source code available? Advanced error reporting AER. After the device uses all of its initial credits, link bandwidth is limited by how fast it receives credit updates.

The debug driver is fully compatible with Windows 32 and 64 bit from XP to Windows 8. The following tables list the performance of the performance of x8, x4, and x1 operations for development boards using the Intel X58 and using this reference design. All forum topics Previous Topic Next Topic. Consequently, it changes depending on the settings specified. After the transfer is complete, the software application uses the counter value to compute the throughput for the transfer and reports it.

The driver configuration is specific to this reference design. You alteta use the init signal as a trigger in the SignalTap II file to capture data. You need a source code license for an IP. Updated with current IP core names.

The maximum read request size is controlled by the device control register bits It continues counting until the last data has been transferred by the DMA module. Made the following changes: Changed the directory name in the “Software Installation” section.
