Since I am working on a 1970's style computer (
blinking lights,
front panel,core memory, big rack with I/O devices) currently
being emulated in FPGA,I have been looking things from that era
rather than the modern stuff. It is sure hard to find a 16 or 32 bit cpu
that has simple byte accessing from that era. That may
be one of the reasons the PDP 11 and/or Unix developed the growth
of more modern software and programming ideas.
Why is byte-granularity in addressing a necessity? It's only an issue
if you have instructions that operate directly on byte quantities in memory.
