Task scheduling in a processing system having a main memory and a processor having a plurality of software-configurable registers is disclosed. The processor may be a synergistic processing unit (SPU) of a cell processor. The processing system operates under the control of a kernel and a program code. A subset of the plurality of software-configurable registers is reserved for use by the kernel. Upon occurrence of an interrupt event requiring control of the processor by the kernel, the kernel may be run on the processor without saving the contents the plurality of registers.
