ASIC - LeFreq/Singularity GitHub Wiki

Application-Specific Integrated Circuits are the way to get more performance. Most people simply don't use or need the general computing power of the computer (Omega(2ⁿ), where most people are quite content using Omega(n²), so break it up. Put the load into hardware. Modern chip fabrication machines can take your verilog file and turn out a chip for it in a matter of hours. So put your OS on an ASIC: less heat, less performance loss, less bugs.

One could also think on motherboard designs. Besides the CPU, one could imagine two processor expansion sockets: FPU, OS chip (replacing the BIOS), BIGINT ALU (with a numerator and denominator preserved for perfect accuracy), multi-media chipset for propagating video processing data, video playback, neural network chip???

The biggest reason for ASICs is to minimize the load on the clock, by putting specialization into HARDWARE. It's a way, you could say, of "meeting GOD halfway".
