LatticeECP2/M DSP Performance
Table 2-11 lists the maximum performance in millions of MAC operations per second (MMAC) for each member of
the LatticeECP2/M family.
Table 2-11. DSP Performance
For further information about the sysDSP block, please see the list of additional technical information at the end of
this data sheet.
Programmable I/O Cells (PIC)
Each PIC contains two PIOs connected to their respective sysI/O buffers as shown in Figure 2-28. The PIO Block
supplies the output data (DO) and the tri-state control signal (TO) to the sysI/O buffer and receives input from the
buffer. Table 2-12 provides the PIO signal list.
