 		 #181309 - 16-bitters

I kind of wonder what happened to the 16-bitters.

They got in a no mans land.

Not quite.

Note for example, that I've posted results for a Microchip 16-bitter in the "dubious benchmark" thread. They come in 2 flavours - as "regular" and as "dsPIC" with enhanced DSP-like arithmetics, and they apparently flourish.

Other successful current 16-bit architectures include the TI's MSP430 and the Infineon's 16-bit offering (mostly successors to the '166, which is a remote descendant of the '51).

As I said in the "dubious benchmark" thread, there's little comparative advantage or disadvantage of any particular databus-width in the typical embedded world; certainly much less than their promoters like to advertise.

NXP suggests 32-bit ARM Cortex-M0 family for 8-bit replaceme            01/01/70 00:00      
   Funny indeed!            01/01/70 00:00

            I've been watching them for 20 years now ...            01/01/70 00:00
