Did I miss secure boot as a feature?

Maybe it's in the spec someplace. Anyone know if it is supported or if it needs to be added?

Both MIPS and PowerPC had ruled the set top box market for years. But I hear some speculation that both Broadcom (MIPS) and ST (own processor) -- two leaders of this market segment -- may be switching to ARM.

From what I've read over the years, they've been mostly ARM or PowerPC, now pretty much all ARM (I suspect).  Marvell makes a lot of these, based on their ARM family which -- ironically -- they bought from Intel (XScale) who in turn had acquired it from DEC (StrongARM).

There may be some MIPS processors in STBs.

Most x86 processors use too much power for a fanless STB.

The real work of an STB nowadays is video decode, which generally needs to be done in a GPU.  So the CPU is mostly doing networking and control -- it doesn't need x86 performance so use something cheap and cool.

JMO/YMMV

Update: I once used an IBM PPC 401GF which was originally designed for STBs.  Delightful little processor: 32-bit PowerPC in an 80-pin TQFP with multiplexed address/data bus.

I was a little surprised to see an ARM chip being targeted for a high-end STB application. Is that unique to the new generation or am I behind the times? My impression was that previous STB devices tended to use Intel or other architectures. I knew that ARM was making significant advancement into areas like this, but I had not realized that they were mainstream.
