The large size is most likely due to the inclusion of debugging information (the -g option). Of course the uof file format will have some overhead for magic numbers and headers, even without debugging information, but most of the extra space comes from the symbols (i.e., strings) included for debugging. I am not a uof file expert, but this is my best guess. Both the assembler and compiler indicate how many instructions were generated with a line like the following: Number of uwords compiled: 620 erik -----Original Message----- From: ravi modgekar [mailto:ravilm@yahoo.com] Sent: Tuesday, July 16, 2002 7:15 AM To: ixp mailing list Subject: Hi, Sorry this question is not related to VERA ,but I thought I could get my answer here. When I compile any of the INTELS SDK 2.01 reference projects ,then the size of the final .uof file is more than the capacity of the control store of the 6 microengines For eg:For the L3Fwd16 reference project the final uof file size is 346KB.Now my questions are 1)How does this 346KB uof file gets loaded into 2kB of control store on all microengines. 2)How do I know when my uof file will exceed the 2kB limit of the control store. 3)Does the Linker throw any exception. Any INTEL guys out there please help me out. Thanks Ravi __________________________________________________ Do You Yahoo!? Yahoo! Autos - Get free new car price quotes http://autos.yahoo.com
