摘要:
A processing core comprising R-number of processing pipelines each comprising N-number of processing paths. Each of the R-number of processing pipelines are synchronized together to operate as a single very long instruction word (VLIW) processing core. The VLIW processing core is configured to process R×N-number of VLIW sub-instructions in parallel. In addition, the R-number of pipelines can be configured to operate independently as separately operating pipelines. In accordance with one embodiment of the present invention, each of the R-number of processing pipelines comprises S-number of register files, such that the processing core comprises R×S-number of register files. In accordance with another embodiment of the present invention, each of the R-number of processing pipelines comprises one register file for every two of the N-number of processing paths, such that S=N/2. In accordance with yet another embodiment of the invention, a single VLIW processing instruction comprises R×N-number of P-bit sub-instructions appended together.
