Replacement for the Intel 80186/286/386/486 Processor in high reliability long life systems

The Force Technologies x86 custom IP core, which is developed for each specific application, offers an elegant and cost-effective way of replicating the core functions of the original processor. Only the functions used by the intended target system are provided, making it viable to emulate in FPGA and thus avoiding the prohibitive cost of recreating the part in silicon.

FT Custom IP cores can replace similar parts such as Intel 80188/80186EB, Intel 80188/80186XL, NEC V53 and AMD AM188/186ES. Recent extensive development work means we can now also emulate the Intel and AMD NMOS 80286, 80386, and 80486 and the later CMOS 80C186, 80286, 80386 and 80486 derivatives.

The IP Core can be targeted to any FPGA from leading vendors such as Altera, Xilinx, Actel and Lattice and has a broad set of integrated peripherals, which helps reduce system development time and cost. It is compatible with a wide range of compilers and debuggers. These include Memory and peripheral Bus interfaces, DMA controller (8237), multiple timers (8254), a programmable interrupt controller (8259), variable-rate asynchronous serial ports (8251), flexible chip select unit, and a peripheral control block.

There are two methods of implementation, a plug in daughterboard to replace the existing processor and a soft implementation to run on an FPGA and peripheral components added to the main system board, this second method offers the possibility of increased system performance.
