Abstract: Systems and methods of data extraction in a vector processor are disclosed. In a particular embodiment a method of data extraction in a vector processor includes copying at least one data element to a source register of a permutation network. The method includes reordering multiple data elements of the source register, populating a destination register of the permutation network with the reordered data elements, and copying the reordered data elements from the destination register to a memory.

Abstract: A method includes selectively coupling a first address line of a plurality of address lines and a second address line of the plurality of address lines to a first element bank of a plurality of element banks of a vector register file according to a selection pattern. The method also includes accessing data stored within the first element bank that is selectively addressed by the first address line via a single read port.

Abstract: Systems and methods for allocation of cache lines in a shared partitioned cache of a multi-threaded processor. A memory management unit is configured to determine attributes associated with an address for a cache entry associated with a processing thread to be allocated in the cache. A configuration register is configured to store cache allocation information based on the determined attributes. A partitioning register is configured to store partitioning information for partitioning the cache into two or more portions. The cache entry is allocated into one of the portions of the cache based on the configuration register and the partitioning register.
