ARM7500 System-on-Chip.
Combines an ARM7 CPU core, 4K cache, VIDC20 and IOMD onto a single chip. It's effectively a RISC PC on a chip (excluding DEBI DMA and the VRAM interface), and was used in the Acorn A7000.
A derivative, the ARM7500FE, was used in the A7000+, A7000+ Odyssey Edition and the Bush Internet TV Set Top Box. The 7500FE is a 7500 with a math co-processor and support for EDO RAM.
