During ‘AmiEXPO 1990’, Jim Hudson from Rockwell International proudly announced that his company is using exclusively Commodore Amiga computers for designing controller chips for the US military department’s new missile program. The engineer from Rockwell International a company based in Atlanta Georgia said that most Intel systems using MS-DOS or Apple Macintosh computers could not compete with the amazing capabilities Commodore Amiga had to offer. At its core, the Amiga has a custom chipset consisting of several coprocessors, which handle audio, video and direct memory access independently of the Central Processing Unit (CPU). This architecture freed up the Amiga’s processor for other tasks and gave the Amiga a performance edge over its competitors. The Motorola 68000 series of microprocessors was used in all Amiga models from Commodore. The MC68000 had a 16-bit external data bus so 32-bits of data is transferred in two consecutive steps, a technique called multiplexing. The MC68000 can address 16 MB of physical memory. Later Amiga models featured higher-speed, full 32-bit CPUs with a larger address space and instruction pipeline facilities. Towards the end of Commodore’s time in charge of Amiga development there were suggestions that Commodore intended to move away from the 68000 series to higher performance RISC processors, such as the PA-RISC. However, these ideas were never developed before Commodore filed for bankruptcy.
