20 / 37 page ![]() Table 16. Variable-Precision DSP Block Configurations for Cyclone V Devices Usage Example Multiplier Size (Bit) DSP Block Resource Low precision fixed point for video applications Three 9 x 9 1 Medium precision fixed point in FIR filters Two 18 x 18 1 FIR filters and general DSP usage Two 18 x 18 with accumulate 1 High precision fixed- or floating-point implementations One 27 x 27 with accumulate 1 You can configure each DSP block during compilation as independent three 9 x 9, two 18 x 18, or one 27 x 27 multipliers. With a dedicated 64 bit cascade bus, you can cascade multiple variable-precision DSP blocks to implement even higher precision DSP functions efficiently. Table 17. Number of Multipliers in Cyclone V Devices The table lists the variable-precision DSP resources by bit precision for each Cyclone V device. Variant Member Code Variable- precision DSP Block Independent Input and Output Multiplications Operator 18 x 18 Multiplier Adder Mode 18 x 18 Multiplier Adder Summed with 36 bit Input 9 x 9 Multiplier 18 x 18 Multiplier 27 x 27 Multiplier Cyclone V E A2 25 75 50 25 25 25 A4 66 198 132 66 66 66 A5 150 450 300 150 150 150 A7 156 468 312 156 156 156 A9 342 1,026 684 342 342 342 Cyclone V GX C3 57 171 114 57 57 57 C4 70 210 140 70 70 70 C5 150 450 300 150 150 150 C7 156 468 312 156 156 156 C9 342 1,026 684 342 342 342 Cyclone V GT D5 150 450 300 150 150 150 D7 156 468 312 156 156 156 D9 342 1,026 684 342 342 342 Cyclone V SE A2 36 108 72 36 36 36 A4 84 252 168 84 84 84 A5 87 261 174 87 87 87 A6 112 336 224 112 112 112 Cyclone V SX C2 36 108 72 36 36 36 C4 84 252 168 84 84 84 C5 87 261 174 87 87 87 continued...
