altfp_mult 的输入应该是浮点表示方式。也就是说，你要仿真3.3*1.1的时候，输入端要是3.3和1.1对应的浮点表示方式。可以用matlab先事先转换好数值。需要说明的这个IP的输出相对输入有好几个周期的延时，6个还是12个，忘了。软件里应该可以看到 你看下这个文件的技术资料啊
hi: i ue quartus 15.0, use max10 10M08SAE144C8GES, i have following questions: 1. when i trying to add ALTFP_MULT ip, it shows: Error (14736):
I am using ALTFP_MULT in the design. This iP is generated using Quartus II 10 special package 1. software. I tried to multiply 3 * 3 using this IP. I
i have a problem when doing a functional simulation on Altera altfp_mult Megafunction: I configured the Megafunction to multiply two 32 bit floats with 5 clock cycles latency, and Modelsim shows me an unknown state of bits 30-23 after 2 clock cycles. However, the ...

For the low-latency option, the latency is determined from the mantissa width. For a mantissa width of 31 to 40 bits, the value is 8 or 18. For a mantissa width of 41 bits or more, the value is 10 or 24. 4.6. ALTFP_DIV Signals 5. ALTFP_MULT IP Core ...

Ted, my custom instruction has the same latency than the ALTFP_MULT module (11 cycles). I´m going to change to 12 or more to see what might happens. Thank you. Translate 0 Kudos Copy link Reply Altera_Forum Honored Contributor II 06-24-2015 02:00 PM...
