Abstract
Apparatus and methods which bundle micro-operations with respect to a vector instruction, dynamically allocate register blocks for a vector instruction, and track the registers using valid bits. A method includes decoding, by a decoder, a vector instruction having a length multiplier of at least two into a number of micro-operations less than the length multiplier, allocating, by an issue queue, an issue queue entry to each of the number of micro-operations and executing, by the issue queue with execution units, each of the number of micro-operations a number of times from the issue queue entry to collectively match the length multiplier.
