TI unveiled today a DSP embedded into DIMM modules. Like Mitsubishi's M32R core, and Siemens' Voice Engine, combining RAM and a core in the same device minimizes bandwidth bottlenecks. Unlike Mitsubishi's solution, TI's would be placed into standard DIMMs, which would appear to be dumb RAM to the OS until it gave commands to the DSP. This architecture should provide great improvements in processing power over classical CPUs. It is also likely to prove popular to RAM manufacturers, who can differentiate their products and avoid all out price wars. More info here.
