No need for AC, but have a look at the new 80296 (a new 80196 + 
stuff) from intel, it has what they call an EPA (event processor 
array), which has been around for a while in the '196, it is 16bit, 
50MHz, fast, has 40bit multiply/accumulate at 12.5 mips, and costs 
next to nothing. IMHO the EPA, plus some other internal goodies, way
surpases the TPU (which is also useful..). These things have 2k 
onboard RAM, a 6MB address space, 512 bytes 3-port register, etc, and 
all the nice programmable chip-select/bus type from the old '186, 
plus more.

Real new, but looking real interesting for those high-grunt 
applications....
