Data compression accelerator methods, apparatus and design structure with improved resource utilization

Methods, apparatus and design structures are provided for improving resource utilization by data compression accelerators. An exemplary apparatus for compressing data comprises a plurality of hardware data compression accelerators and a hash table shared by the plurality of hardware data compression accelerators. Each of the plurality of hardware data compression accelerators optionally comprises a first-in-first-out buffer that stores one or more input phrases. The hash table optionally records a location in the first-in-first-out buffers where a previous instance of an input phrase is stored. The plurality of hardware data compression accelerators can simultaneously access the hash table. For example, the hash table optionally comprises a plurality of input ports for simultaneous access of the hash table by the plurality of hardware data compression accelerators. A design structure for a data compression accelerator system is also disclosed.
