Hi, Does the TMS320C6711 DSP chip provide support for IEEE 754? How can we ascertain this? Thanks in advance, Regards, Nalin |

C3x floating point format is not compatible with IEEE 754. I believe this decision was made because it was easier/faster to support another format in those devices. C4x is also not compatible, but does have instructions to convert to and from IEEE (TOIEEE/FRIEEE). 6711 does include support for IEEE 754 single and double precision in hardware. -----Original Message----- From: Jeff Brower [mailto:] Sent: Friday, October 18, 2002 10:09 AM To: Nalin K Pithwa Cc: Subject: Re: [c6x] IEEE 754 support Nalin K Pithwa- > Does the TMS320C6711 DSP chip provide support for IEEE 754?

Nalin- Brian is correct. I got out the old C3x and C4x books and checked.
