Lattice Semiconductor
IPexpress™
The user can access the sysDSP block via the ispLEVER IPexpress tool, which provides the option to configure
each DSP module (or group of modules), or by direct HDL instantiation. In addition, Lattice has partnered with The
MathWorks
ispLEVER to dramatically shorten the DSP design cycle in Lattice FPGAs.
Optimized DSP Functions
Lattice provides a library of optimized DSP IP functions. Some of the IP cores planned for the LatticeXP2 DSP
include the Bit Correlator, FFT functions, FIR Filter, Reed-Solomon Encoder/Decoder, Turbo Encoder/Decoder and
Convolutional Encoder/Decoder. Please contact Lattice to obtain the latest list of available DSP IP cores.
Resources Available in the LatticeXP2 Family
Table 2-8 shows the maximum number of multipliers for each member of the LatticeXP2 family. Table 2-9 shows the
maximum available EBR RAM Blocks and Serial TAG Memory bits in each LatticeXP2 device. EBR blocks,
together with Distributed RAM can be used to store variables locally for fast DSP operations.

LatticeXP2 DSP Performance
Table 2-10 lists the maximum performance in Millions of MAC (MMAC) operations per second for each member of
the LatticeXP2 family.
