Abstract
Efficient and scalable circuitry for performing Cholesky decomposition is based on a dataflow style architecture which uses self-timed circuitry and eliminates the need for complicated state machines. Calculations are ordered such that partial sums of products are created in parallel subject to data dependency requirements, allowing a single accumulator to perform the summation. A Vector FIFO receives a partial sum of products from a vector processing engine. A Feedback FIFO stores partial results and feeds the partial results back to the data path based on signals from a dataflow controller. The circuitry is flexible to allow different matrix sizes, speed grades, and target frequencies without recompilation.
