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.
