This should do the trick: 
my $templateformat = 'w<NM>b<NM>cm<CH>sw<SW>';
my $inputexample = 'w8b8cm512swno';

my @splittemplate = split /[^A-Z]+/,$templateformat;

[download]
my @splitinput = split /\D+/,$inputexample; 
my @splitinput = split /[^(\d)(no)]+/,$inputexample;

Update:
Include "no" as an element of the second array.

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
