Abstract
A parallel computer processor that performs L1 norm calculations includes a plurality of processing elements and a data pipeline which couples the processing elements. The data vectors for which the L1 norm is to be calculated are stored in storage lines of a cache memory. In operation each processing element accesses data in its private storage column in the cache memory and calculates a term signal. The term signals are added to form the resulting L1 norm.
