Lattice Semiconductor
IPexpress™
The user can access the sysDSP block via the IPexpress configuration tool, included with the ispLEVER design
tool suite. IPexpress has options to configure each DSP module (or group of modules) or through direct HDL
instantiation. Additionally Lattice has partnered Mathworks to support instantiation in the Simulink tool, which is a
Graphical Simulation Environment. Simulink works with ispLEVER and dramatically shortens the DSP design cycle
in Lattice FPGAs.
Optimized DSP Functions
Lattice provides a library of optimized DSP IP functions. Some of the IPs planned for LatticeECP DSP are: Bit Cor-
relators, Fast Fourier Transform, Finite Impulse Response (FIR) Filter, Reed-Solomon Encoder/ Decoder, Turbo
Encoder/Decoders and Convolutional Encoder/Decoder. Please contact Lattice to obtain the latest list of available
DSP IPs.
Resources Available in the LatticeECP Family
Table 2-9 shows the maximum number of multipliers for each member of the LatticeECP family. Table 2-10 shows
the maximum available EBR RAM Blocks in each of the LatticeECP family. EBR blocks, together with Distributed
RAM can be used to store variables locally for the fast DSP operations.

DSP Performance of the LatticeECP Family
Table 2-11 lists the maximum performance in millions of MAC operations per second (MMAC) for each member of
the LatticeECP family.
