摘要： A mapper unit of an out-of-order processor assigns a particular counter currently in a counter free pool to count a number of mappings of logical registers to a particular physical register from among multiple physical registers, responsive to an execution of an instruction by the mapper unit mapping at least one logical register to the particular physical register. The number of counters is less than the number of physical registers. The mapper unit, responsive to the counted number of mappings of logical registers to the particular physical register decremented to less than a minimum value, returns the particular counter to the counter free pool.

摘要： A system for co-generation of electricity combining a hydrocarbon catalytic reformer, an SOFC assembly and a generator driven by a gas turbine. The fuel cell assembly recycles a high percentage of anode exhaust gas into the reformer. Oxygen for reforming is derived from water in an endothermic process. The stack exit temperature is normally above 800° C. DC power from the fuel cell assembly and AC power from the gas turbine generator are directed to a power conditioner. Anode exhaust gas including carbon monoxide and hydrogen is divided into a plurality of portions by which heat may be added to the reforming, gas turbine, and cathode air heating processes. Water may be recovered from the exhaust. A power system in accordance with the invention is capable of operating at a higher total efficiency than either the fuel cell component or the gas turbine component alone.

摘要： A dual-issue instruction is decoded to determine a plurality of LSU dependencies needed by an LSU part of the dual-issue instruction and a plurality of non-LSU dependencies needed by a non-LSU part of the dual-issue instruction. During dispatch of the dual-issue instruction by the microprocessor, the dual dependency matrices are employed as follows: a Load-Store Unit (LSU) dependency matrix is written with the plurality of LSU dependencies and a non-LSU dependency matrix is written with the plurality of non-LSU dependencies; an LSU issue valid (LSU IV) indicator is set as valid to issue; an LSU portion of the dual-issue instruction is issued once the plurality of LSU dependencies of the dual issue instruction are satisfied; a non-LSU issue valid (non-LSU IV) indicator is set as valid to issue; and a non-LSU portion of the dual-issue instruction is issued once the plurality of non-LSU dependencies of the dual issue instruction are satisfied. The LSU dependency matrix and the non-LSU dependency matrix can then be notified that one or more instructions dependent upon the dual-issue instruction may now issue.

摘要： A solid-oxide fuel cell system wherein a reformate combustor is disposed in the reformate flow path between a hydrocarbon reformer and a fuel cell stack. At system start-up, reformate is partially burned within the combustor by admitting combustion air, and the partially-burned reformate is passed through the anode chambers of the stack to warm the anodes. In addition, reformate is passed through a cathode-air heat exchanger to warm combustion air entering the cathode chambers of the stack. The combustor may continue to be supplied with a low level of air during steady-state operation of the SOFC, thereby providing a moist environment within the anode chambers to prevent coking of the anodes and providing additional heat to the reformate. The combustor decouples the reformer from the stack thermodynamically, permitting the reformer and the stack each to run in its own optimal temperature range.
