The present invention relates to configuring search spaces of at least two coexisting control channels in a communication system. Programmable input amplifiers are programmed to be transmissive or blocking through fusesantifuses so that selection signals applied to the selection contact points either activate or block functional elements only of one or only of the other semiconductor chip. For one or more identified songs, song metadata is sent to the client computing system, and a geolocation of the client computing system is identified based on the location data. The runtime generated code and native binary code can be cached in a machine-wide cache, or can be added to the metadata of the assembly generated from the source code of the program entity.
