Conversion from IEEE754

Hello, is there a way to convert IEEE754 format to 1750a 32 bit or 48 bit format?

[Walter Roberson]

1750A here appears to refer to MIL-STD-1750A, a military computer specification from 1980.

I have not yet found any information about the 48 bit format, but the 32 bit floating point format uses

f * 2^e

where f is a 24 bit 2's complement fraction with no bias, and e is an 8 bit 2's complement exponent with no bias.

I have not yet located the bit ordering information.

I think I found some information on it. however, i'm new to simulink and not sure how to implement this. any advice?

[Walter Roberson]

It would help people if you could post the links to the format descriptions (or just the descriptions themselves if they are short enough.)

I won't be able to help you directly with the Simulink aspect, but I might be able to suggest matlab conversion code.

Here is the link to the format I'm using. It is section 5.0 for extended precision.

Hi Pika,

One possible approach would be created a custom MATLAB function block that implements the conversion algorithm, then write MATLAB code within the block to perform the conversion logic from IEEE754 to 1750A format.
