Enhanced wiring structure for a cache supporting auxiliary data output

摘要

A mechanism is provided in a data processing system for enhancing wiring structure for a cache supporting an auxiliary data output. The mechanism splits the data cache into a first data portion and a second data portion. The first data portion provides a first set of data elements and the second data portion provides a second set of data elements. The mechanism connects a first data path to provide the first set of data elements to a primary output and connects a second data path to provide the second set of data elements to the primary output. The mechanism feeds the first data path back into the second data path and feeds the second data path back into the first data path. The mechanism connects a secondary output to the second data path.

1. A method, in a data processing system, for enhancing wiring structure for a cache supporting an auxiliary data output, the method comprising:
splitting the data cache into a first data portion and a second data portion, wherein the first data portion provides a first set of data elements and the second data portion provides a second set of data elements; connecting a first data path to provide the first set of data elements to a primary output; connecting a second data path to provide the second set of data elements to the primary output; feeding the first data path back into the second data path and feeding the second data path back into the first data path; and connecting a secondary output to the second data path such that a first subset of the first set of data elements and a first subset of the second set of data elements are provided to the secondary output in a first configuration and a second subset of the first set of data elements and a second subset of the second set of data elements are provided to the secondary output in a second configuration.
