Manufactures other vendors' end-of-lifed chips under licence, on a built-to-order basis. Later developed independent x86 CPU designs.Ĭontinued to manufacture x86 CPUs after being spun off from Harris in 1999. Manufactured and sold under its own name of x86-processors designed by others Įarly Intel x86 CPU designs (up to the 80286) have in the past been second-sourced by the following manufacturers under licence from Intel: Manufacturer DEC (manufactured 486 processors for AMD discontinued x86 production).National Semiconductor (manufactured processors for ZF Micro discontinued x86 production).UMC (manufactured processors for Rise, SiS, ALi, ULi and Nvidia discontinued x86 production).Fujitsu (manufactures processors for VIA manufactured processors for Transmeta).TSMC (manufactures processors for AMD and VIA discontinued production for Transmeta).IBM (manufactures processors for ZF Micro and VIA discontinued production for NexGen and Transmeta).GlobalFoundries (manufactures processors for AMD).Manufacturing-only of x86-processors designed by others Zet open source 80186 compatible FPGA implementation targeting the Xilinx ML403 and Altera DE1.S80186 open source 80186 compatible FPGA implementation.

ao486 open source FPGA implementation of the 486SX (currently targets the Terasic Altera DE2-115).

VAutomation - offered synthesizable x86 cores, in particular the Turbo 186, that has been implemented in ASICs from numerous vendors, e.g.

Intersil (x86 line, that is up to 80286 compatible, discontinued).

Vadem - VG230 and VG330 (SoCs with NEC V30 CPU cores, manufacturing continued by Amphus).

Innovasic - pin-compatible 80186/80188 clones.

Advantech - EVA-X4150 and EVA-X4300 (SoCs with 486SX-compatible processors at 150MHz and 300MHz, respectively).

Auctor / ACC Micro - Maple SoC (Cx486DX4 core at 100-133 Mhz).
