HD-CB maps environmental states into a high-dimensional space\, representing actions with dedicated hypervectors that are updated in real-time based on received rewards. By operating directly in the high- dimensional space\, HD-CB replaces traditional\, computationally expensive methods\, like ridge regression\, with efficient and highly parallel vect or operations\, achieving superior performance\, faster convergence\, and improved scalability.\nAbstract 2: With its inherent parallelism\, Hyperdi mensional Computing is an ideal candidate for hardware implementation. Thi s talk introduces HDCU\, a reconfigurable hardware accelerator powered by a novel RISC-V instruction set extension. HDCU accelerates core arithmetic operations on hypervectors and can be configured at synthesis time to bal ance execution speed and resource usage\, adapting to diverse applications . A custom RISC-V Instruction Set Extension is designed to efficiently con trol the accelerator\, with instructions fully integrated into the GCC com piler chain and exposed to the programmer as intrinsic function calls. The dual flexibility coming from hardware configuration and software programm ability sets this work apart from application-specific solutions in the li terature\, offering a unique\, versatile accelerator adaptable to a wide r ange of applications and learning tasks.\n\nBest\,\nEvgeny\n\n\n\n UID:040000008200E00074C5B7101A82E00800000000BD82B3DBE282DB01000000000000000 010000000FF62CF8596C1614F97ECA40869907397 SUMMARY;LANGUAGE=en-GB:VSAONLINE-10.
