摘要
Control logic of a node controller receives an input vector and produces an output vector. The control logic includes a plurality of tied control store entries including hard-coded logic to identify unique values of the input vector and to produce the output vector from a hard-coded output vector when the input vector is identified and when the tied control store is enabled. The control logic also includes a plurality of spare control store entries including programmable logic configurable to identify values of the input vector and to produce the output vector from a programmable output vector when the input vector is identified and when the spare control store is enabled. One of the spare control store entries that is configured to identify a value of the input vector that none of the tied control store entries that are enabled by the entry-enables register are configured to identify is enabled.
