I worked on one of the first dual core processors when I was at C-Cube Microsystems way back in 2000. It was an SoC with two microSPARC cores. One core was a general purpose processor for system functions running VxWorks and the other core was an MPEG-2 encoder/decoder running bare metal. There was no MMU and the direct mapped data caches were not coherent (data segments had to be padded to a cache line to avoid the processors overwriting each others memory). The chip was designed by Les Kohn of i860 fame. Here's a pic of an engineering sample with a 2001 date code. https://www.w6rz.net/domino.png https://www.w6rz.net/domino.png
