Lattice Semiconductor
ALU Flags
The sysDSP slice provides a number of flags from the ALU including:
Clock, Clock Enable and Reset Resources
Global Clock, Clock Enable and Reset signals from routing are available to every sysDSP slice. From four clock
sources (CLK0, CLK1, CLK2, and CLK3) one clock is selected for each input register, pipeline register and output
register. Similarly Clock Enable (CE) and Reset (RST) are selected at each input register, pipeline register and out-
put register.
Resources Available in the LatticeECP3 Family
Table 2-9 shows the maximum number of multipliers for each member of the LatticeECP3 family. Table 2-10 shows
the maximum available EBR RAM Blocks in each LatticeECP3 device. EBR blocks, together with Distributed RAM
can be used to store variables locally for fast DSP operations.
