Abstract
A control store unit having a control store address generator able to provide both the normal control store address generation functions, and the BIST/logout address generation functions. In response to a test enable signal, the address generator switches between two modes: a normal mode and a test mode. Under the normal mode, normal control store addresses are generated. Under the test mode, a sequence of BIST/logout addresses are generated that sequentially cycles through the entire control store memory at full CPU speed.
