Digital Signal Processing (DSP) Block

A digital signal processing (DSP) block implements specific support for common fixed-point and floating-point arithmetic, which reduces the need to build equivalent logic from general-purpose ALMs.
The following figure illustrates a simplified three-input DSP block consisting of a multiplier (×) and an adder (+):

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
