A new processor is able to decode any signal to eliminate transmission errors extremely quickly. This would remove the need to install a specific chip for each type of encoding, and would increase the performance of video games, virtual reality and 5G networks …

A team of researchers from Massachusetts Institute of Technology (MIT) and Boston University in the United States, as well as the National University of Ireland at Maynooth, have just developed a new processor which should bypass the need for a specialized chip for correct the mistakes in each type of information transmission.
When data is sent over a network, electromagnetic disturbances can corrupt the information. The data is therefore encoded, to then be decoded at the time of reception by an algorithm which can use this code to rectify the data. bugs. However, these complex calculations generally require a dedicated chip, different for each type of network.
A processor that guesses the type of interference
This new processor is based on an algorithm named “Grand” (Guessing Random Additive Noise Decoding), which works in the opposite way to the usual systems. He guesses what kind ofinterference the data may have encountered, and generates noise to subtract it from the signal and see if it matches a known code. This chip incorporates a three-level architecture capable of generating a simple noise and two other more complex noises, and which operate in parallel.
This approach allows the chip to be able to process any type of coding, provided that there is a correspondence table for them. codes. It’s fast and only adds a microsecond delay for 128-bit code. This processor would eliminate the need for a specialized chip for each code, and allow innovations in this area since it could adapt to new codes. It should also improve the performance for data transmission in the fields of video games, of that of the augmented reality and virtual, 5G networks and connected objects.
