32 / 386 page ![]() 2-29 Architecture Lattice Semiconductor LatticeECP2/M Family Data Sheet 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.
