Lattice Semiconductor
This allows designers to use highly parallel implementations of DSP functions. Designers can optimize DSP perfor-
mance vs. area by choosing appropriate levels of parallelism. Figure 2-23 compares the fully serial implementation
to the mixed parallel and serial implementation.

LatticeECP3 sysDSP Slice Architecture Features
The LatticeECP3 sysDSP Slice has been significantly enhanced to provide functions needed for advanced pro-
cessing applications. These enhancements provide improved flexibility and resource utilization.
The LatticeECP3 sysDSP Slice supports many functions that include the following:
• Multiply (one 18x36, two 18x18 or four 9x9 Multiplies per Slice)
• Multiply (36x36 by cascading across two sysDSP slices)
• Multiply Accumulate (up to 18x36 Multipliers feeding an Accumulator that can have up to 54-bit resolution)
• Two Multiplies feeding one Accumulate per cycle for increased processing with lower latency (two 18x18 Mul-
• Flexible saturation and rounding options to satisfy a diverse set of applications situations
• Flexible cascading across DSP slices
• Flexible and Powerful Arithmetic Logic Unit (ALU) Supports:
tiplies feed into an accumulator that can accumulate up to 52 bits)
– Minimizes fabric use for common DSP and ALU functions
– Enables implementation of FIR Filter or similar structures using dedicated sysDSP slice resources only
– Provides matching pipeline registers
– Can be configured to continue cascading from one row of sysDSP slices to another for longer cascade
– Dynamically selectable ALU OPCODE
– Ternary arithmetic (addition/subtraction of three inputs)
– Bit-wise two-input logic operations (AND, OR, NAND, NOR, XOR and XNOR)
– Eight flexible and programmable ALU flags that can be used for multiple pattern detection scenarios, such
chains
