Performance and Resource Utilization

Preliminary

You only need to purchase a license for the megafunction when you are completely

satisfied with its functionality and performance, and want to take your design to

production.

f For more information on OpenCore Plus hardware evaluation using the POS-PHY

Level 2 and 3 Compiler, see “OpenCore Plus Time-Out Behavior” on page 3–6 and AN

320: OpenCore Plus Evaluation of Megafunctions.

Performance and Resource Utilization

Table 1–3 through 1–7 show typical expected performance for SPHY and 4-port POS-

PHY MegaCore functions. All results are push-button performance and use a FIFO

buffer size of 512 bytes. These results were obtained using the Quartus

II software

version for the following devices:

■ Cyclone II (see tables for device details)

■ Cyclone III (EP3C5F256C6 for POS-PHY level 3)

■ Stratix III (EP3SL70F484C2 for POS-PHY level 2; EP3SL50F484C2 for POS-PHY

level 3)

■ Stratix IV (EP4SGX70DF29C2X )
