#189845 - multi-threaded Responding to: ???'s previous message |

Another attractive use case might be building an interconnected crowd of small CPUs as an alternative to a large CPU running a multi-threaded application on a RTOS. This can be done more conveniently inside an FPGA (*really small* soft CPUs that can be programmed in C are hard to come by but that's another story). There is one company (HoChip) making multi-threaded 8051, and this is one area where a Soft-CPU could make educational sense. That said, besides the core itself, a weakness in FPGA pathway remains code storage, and it is hard to get the Logic Fabric plus Code storage, for anything like the same price of a real chip. As an example, the new AT89LP52 is only 65c/100+, and gives a very capable basic core. |
