When most people think of artificial intelligence, they imagine highly complex software code. But if you look under the hood of today’s most advanced deep learning algorithms, you won’t find traditional programming logic—you will find an endless ocean of matrix mathematics.
The fundamental difference between how AI “thinks” and how traditional software operates is exactly why our current digital chips are hitting a wall, and why the future of AI demands an entirely new hardware architecture.
The End of “Divide and Conquer” For the past 75 years, computing has operated on the same foundational principles: human programmers write explicit rules, logic, and control structures to produce deterministic outputs. Traditional programs rely on a “divide and conquer” approach, breaking massive problems down into small, manageable pieces that can be processed sequentially.
Machine learning operates entirely differently. Rather than following explicitly written rules, AI applications rely on end-to-end learning models that treat the entire neural network as a probabilistic “black box”. AI models cannot easily be broken down into small modular tasks; they must be loaded and executed as massive, monolithic units to derive patterns and make predictions.
The Math Behind the Magic Instead of using standard logic gates, deep learning algorithms like Convolutional Neural Networks (CNNs) and Transformers are fundamentally built on matrix operations—specifically multiply-accumulate (MAC) and vector-matrix multiplication (VMM) tasks.
When an AI model is processing data, it is essentially adjusting weights and biases through millions of simultaneous calculations. The sheer volume of these mathematical operations is staggering. In massive large language models like GPT-3, vector-matrix multiplications make up an estimated 90% to 92% of the entire processing effort.
Why Current Chips are Choking on Math The core issue holding AI back is that our current hardware was designed for the “divide and conquer” era of traditional software. Traditional processors are optimized to load small pieces of code and data into a fast cache to execute them quickly.
However, AI models require loading gigantic datasets and model parameters in bulk. Because traditional von Neumann architecture physically separates the memory from the processor, these massive matrices of data must be constantly shipped back and forth across a data bus just to perform the necessary math. As AI models grow exponentially larger, this creates a severe bottleneck that slows down performance and drains massive amounts of energy. We are trying to run the world’s heaviest mathematical workloads on hardware designed to process sequential logic.
The Hardware Paradigm Shift To continue scaling AI, we cannot rely on the architectures of the past. The industry must undergo a computing paradigm shift toward In-Memory Computing (IMC).
By integrating computation directly into the physical location where the data is stored, IMC completely eliminates the need to constantly shuffle massive matrices across a data bus. Utilizing an analog crossbar array, this architecture actually uses physical laws—like Ohm’s Law and Kirchhoff’s Current Law—to execute mathematical summation and multiplication naturally. Because the current in each memory cell is generated simultaneously, the vector-matrix multiplications required by AI become massively parallel.
