Methods To Double The Number Of Registers On ARM Processors

In register connection, more number of registers are made available to the compiler and the programmer by mapping the architectural registers to the physical registers. This increases the number of register on the ARM Processor i.e. it doubles the number of registers. However, this method has a drawback that it changes the size of the code significantly. A bigger code will hence take longer time to execute and also it makes the code complex.
