Stratix® II, Stratix, Stratix GX, Cyclone™ II, and Cyclone devices have
dedicated architectural features that make it easy to implement highperformance
multipliers. Stratix II, Stratix, and Stratix GX devices feature
embedded high-performance multiplier-accumulators (MACs) in
dedicated digital signal processing (DSP) blocks. DSP blocks can operate
at data rates above 300 million samples per second (MSPS), making
Stratix II, Stratix, and Stratix GX devices ideal for high-speed DSP
applications. Cyclone II devices have embedded multiplier blocks for
DSP.
In addition to the dedicated DSP blocks, designers can also use the
Stratix II, Stratix, and Stratix GX devices’ TriMatrix™ memory blocks to
implement high-performance soft multipliers of variable depths and
widths. For example, designers can useTriMatrix memory blocks as lookup
tables (LUTs) that contain partial results from multiplication of input
data with coefficients. Cyclone II and Cyclone devices have M4K memory
blocks which can be used as LUTs to implement variable depth/width
high-performance soft multipliers for low cost, high volume DSP
applications.
