open format for describing binary data in hexadecimal notation. SHF
provides the ability to describe both small and large, simple and
complex hexadecimal data dumps in an open, modern, transport- and
computing, network, and embedded systems communities, several
different types of data formats for hexadecimal data are being used.
One of the more common formats is known as "S-records" (and several
derivatives), which reportedly originated at the Motorola company.
The S Hexdump Format is named in its honour.
Typical uses of
these dump formats include executable object code for
embedded systems (i.e., "firmware"), on-chip flash memories and
filesystems, FPGA configuration bitstreams, graphics and other
application resources, routing tables, etc. Unfortunately, none of
the formats used are truly open, vendor-neutral, and/or well-defined.
Even more problematic
is the fact that none of these formats are able
to represent the large data sizes that are getting more and more
common. Data dumps comprised of multiple sub-blocks with different
