Re: Help w/ ADSP-21489... DUAL SIMD MAC 40bit Floating Point

Hi Jithul,

 

In keeping with the 64-bit width limit (SIMD or not), please help me use 40-bit FP variables (since they encode 9+ decimal digits) in an efficient way that does not attempt to use SIMD and the PEx/PEy register sets. I've attached a draft edit of your mapping diagram that attempts to use the PX register and deal with 40-bit FP variables. Please give me some idea about the Assembler Code needed to LOAD then STORE registers like F0 and F4.

 

Best Regards,

Rich
