Platform Details
xilinx_u250_gen3x16_xdma_4_1 is a DFX-2RP two-stage platform, which consists of both a base and shell partition. The platform implements the device floorplan shown in the following figure and uses resources across the multiple super logic regions (SLR) of the device. The static and dynamic regions are shown across the SLRs, along with the available DDR memory connections associated with each SLR.
To get the same information for development platforms, if you
install the Vitis unified software platform,
use the platforminfo command utility. It reports
information on interfaces, clocks, valid SLRs, allocated resources, and memory in a
structured format. For more information, see
platforminfo Utility in the
Application Acceleration Development flow of the Vitis Unified Software Platform Documentation
(UG1416).
Memory
The Alveo U250 card has a total of four available DDR memory banks. In addition, it is possible to use device logic resources for small, fast, on-chip memory accesses as PLRAM. The following table lists the allocation of memory resources per SLR.
| Resources | SLR 0 | SLR 1 | SLR 2 | SLR3 |
|---|---|---|---|---|
| DDR memory channels (system port name) | DDR[0] (16 GB DDR4) | DDR[1] (16 GB DDR4) | DDR[2] (16 GB DDR4) | DDR[3] (16 GB DDR4) |
| PLRAM memory channels (system port name) | PLRAM[0] (128K, Block RAM) | PLRAM[1] (128K Block RAM) | PLRAM[2] (128K Block RAM) | PLRAM[3] (128K Block RAM) |
| Host memory channels (system port name) | No connections | No connections | HOST[0] 16 GB on host | No connections |
Clocking
The platform provides a 300 MHz default clock to run the accelerator.
Available Resources After Platform Installation
The following table lists the available resources in the dynamic region of each SLR. It represents the total device resources after subtracting those used by the static region.
| Resource | SLR 0 | SLR 1 | SLR 2 | SLR 3 |
|---|---|---|---|---|
| CLB LUT | 420K | 205K | 407K | 424K |
| CLB register | 840K | 411K | 815K | 849K |
| Block RAM tile | 668 | 384 | 660 | 672 |
| UltraRAM | 312 | 128 | 308 | 320 |
| DSP | 3032 | 1536 | 2994 | 3072 |
