Abstract
Systems, methods, and apparatuses relating to swizzle operations and disable operations in a configurable spatial accelerator (CSA) are described. Certain embodiments herein provide for an encoding system for a specific set of swizzle primitives across a plurality of packed data elements in a CSA. In one embodiment, a CSA includes a plurality of processing elements, a circuit switched interconnect network between the plurality of processing elements, and a configuration register within each processing element to store a configuration value having a first portion that, when set to a first value that indicates a first mode, causes the processing element to pass an input value to operation circuitry of the processing element without modifying the input value, and, when set to a second value that indicates a second mode, causes the processing element to perform a swizzle operation on the input value to form a swizzled input value before sending the swizzled input value to the operation circuitry of the processing element, and a second portion that causes the processing element to perform an operation indicated by the second portion the configuration value on the input value in the firs…
