Ordering Part Number
The Ordering Part Number (OPN) for all configurations of the Turbo Decoder core targeting LatticeECP2 devices is
TURBO-ENCO-P2-U3. Table 1 lists the parameter settings that are available for the Turbo Decoder. Use the IPex-
press software tool to help generate new configurations of this IP core. IPexpress is the Lattice IP configuration util-
ity, and is included as a standard feature of the ispLEVER design tools. Details regarding the usage of IPexpress
can be found in the IPexpress and ispLEVER help system. For more information on the ispLEVER design tools,

1. Performance and utilization characteristics are generated using LFE2-70E-7F672C, with Lattice's ispLEVER v.7.1 SP1 soft-
ware. When using this IP core in a different density, speed, or grade within the LatticeECP2 family, performance and utiliza-
tion may vary.
