Neuromorphic chips are one of the most promising new technologies, alongside quantum computers. Making a uni-processor faster without increasing the allowed transfer rate in the throughput will result in no advantage to the end user.

Sales. For the third consecutive year, U.S. business-to-business channel sales (sales through distributors and commercial resellers) increased, ending 2013 up nearly 6 percent at $61.7 billion. July 16th, 2019 - By: Brian Bailey. It is possible to make the CPU run at a high data transfer rate because data is moved between locations inside them across tiny distances. The Von Neumann Bottleneck Dominique Thiebaut CSC103 October 2012. The impressive growth was the fastest sales increase since the end of the recession. This limitation, known as the von Neumann bottleneck, can overshadow the actual computing time, especially in neural networks – which depend on large vector-matrix multiplications. Research institutes and companies around the world are working on novel computers that function fundamentally differently from the von Neumann architecture. The von Neumann bottleneck posits that the speed and efficiency of computation is limited by the time it takes to transfer data between chips, and in the meantime the much faster computational chip remains idle. Resolving this so called “von Neumann bottleneck” requires developing completely new computing technologies. The von Neumann bottleneck is one of the largest impediments in modern technology. In recent history, the Von Neumann bottleneck has become more apparent. The design philosophy of modern computers is based upon a physically separate CPU and main memory. It must wait until the data has been written before proceeding and vice versa.

Changes that sidestep von Neumann architecture could be key to low-power ML hardware. The cost associated with moving data in and out of memory is becoming prohibitive, both in terms of performance and power, and it is being made worse by the data locality in algorithms, which limits the effectiveness of cache. This is referred to as the Von Neumann bottleneck and often limits the performance of the system. condition called the von Neumann bottleneck, it places a limitation on how fast the processor can run. Instructions and data must share the same path to the CPU from memory, so if the CPU is writing a data value out to memory, it cannot fetch the next instruction to be executed.
