We found that the first line uses double precision and the second line uses float. Is the long running time due to inconsistent data types? What is the difference between double precision operation and single precision operation in mpc5744p? Is there a special 64 bit multiplier in mpc5744p?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="9225f1d7c7591265.png" style="width: 444px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/179040i2E3A8F2C210FD537/image-size/large?v=v2&amp;px=999" role="button" title="9225f1d7c7591265.png" alt="9225f1d7c7591265.png" /></span></P> Fri, 06 May 2022 11:28:22 GMT https://community.nxp.com/t5/MPC5xxx/MPC5744P-Data-multiplication-operation-time/m-p/1454193#M21127 XSL-WF 2022-05-06T11:28:22Z https://community.nxp.com/t5/MPC5xxx/MPC5744P-Data-multiplication-operation-time/m-p/1462383#M21227 <P>Hi, apparently it is because MPC5644P use EFPU engine natively supporting 32-bit floating point operations. 64-bit calculation are SW emulated.</P> Mon, 23 May 2022 10:39:58 GMT https://community.nxp.com/t5/MPC5xxx/MPC5744P-Data-multiplication-operation-time/m-p/1462383#M21227 davidtosenovjan 2022-05-23T10:39:58Z https://community.nxp.com/t5/MPC5xxx/MPC5744P-Data-multiplication-operation-time/m-p/1463692#M21238 <P>tkank you!</P> Wed, 25 May 2022 05:39:48 GMT https://community.nxp.com/t5/MPC5xxx/MPC5744P-Data-multiplication-operation-time/m-p/1463692#M21238 XSL-WF 2022-05-25T05:39:48Z
