Abstract
A link address/sequential address generation circuit is provided for generating a link/sequential address. The circuit receives the most significant bits of at least two addresses: a first address of a first set of bytes including a branch instruction and a second address of a second set of bytes contiguous to the first set. The least significant bits of the branch PC (those bits not included in the most significant bits of the addresses received by the circuit) are used to generate the least significant bits of the link/sequential address and to select one of the first address and the second address to supply the most significant bits.
