We just posted a video demonstration of a Quad Core MCL51 on YouTube:

 

Each core is running an independent application program.

Core-0: Parallel Port Blaster
Core-1: MIDI music player
Core-2: Sine wave generator using a R-2R DAC
Core-3: 115,200 UART Blaster

Four MCL51 8051 cores are instantiated along with a dual 24-bit timer and a UART.

A total of 1227 Artix-7 LUTs are consumed by this quad core processor which is less logic than most single core gate-based 8051 cores!
