You _already_ are getting three on a chip. They just have a common program counter. Not much more space needed to add a program counter for each processor and there you are... new microprocessors are going to soon support threading anyway, internal to the cpu, so that the cpu is executing multiple instruction streams all the time, to overlap execution and memory access among other things.
