ABSTRACT:
A method for broadcasting instructions/data to a plurality of processors in a multiprocessor device via aliasing is provided. In order to broadcast data to a plurality of processors, a control processor writes to the registers that store the identifiers of the processors and sets two or more of these registers to a same value. The control processor may write the desired data/instructions to be broadcast to a portion of memory corresponding to the starting address associated with the processor identifier of the two or more processors. When the two or more processors look for a starting address of their local store from which to read, the two or more processors will identify the same starting address, essentially aliasing the memory region. The two or more processors will read the instructions/data from the same aliased memory region starting at the identified starting address and process the same instructions/data.
