3.3.1. Operational Modes

The Intel® Quartus® Prime software includes IP cores that you can use to control the operation mode of the multipliers. After entering the parameter settings with the IP Catalog, the Intel® Quartus® Prime software automatically configures the variable precision DSP block.

Variable-precision DSP block can also be implemented using DSP Builder for Intel® FPGAs and OpenCL™.

Table 20.  Operational Modes
Fixed-Point Arithmetic Floating-Point Arithmetic

Intel provides two methods for implementing various modes of the Intel® Arria® 10 variable precision DSP block in a design—using the Intel® Quartus® Prime DSP IP core and HDL inferring.

The following Intel® Quartus® Prime IP cores are supported for the Intel® Arria® 10 variable precision DSP blocks in the fixed-point arithmetic implementation:
  • Intel FPGA Multiply Adder
  • ALTMULT_COMPLEX
  • Intel Arria 10 Native Fixed Point DSP IP core
