Abstract
Methods and apparatus are provided for efficiently executing extended custom instructions on a programmable chip. Components of a processor core such as arithmetic logic units, program sequencer units, and address generation units are integrated with customizable logic blocks. Various customizable logic blocks can be invoked in a pipelined manner using an available customized instruction set while allowing a processor to continue simultaneous operation. Program counter snooping is also provided to add custom instruction functionality to a processor with no additional provisions for adding custom instructions.
