Abstract
Apparatus and methods for cracking and processing vector instructions in a vector pipeline after decoding of a single or a first micro-operation in a main or primary pipeline are described. An integrated circuit includes a primary pipeline to decode a micro-operation from an instruction, create a reorder buffer entry in a reorder buffer for the micro-operation, responsive to a determination that the instruction is a vector instruction, send the micro-operation to a vector pipeline, and responsive to a determination that the instruction is a multiple register vector instruction, signal a vector pipeline to decode a remaining micro-operations from the instruction, and the vector pipeline to process the micro-operation, and process the remaining micro-operations when the instruction is the multiple register vector instruction.
