Filed: 1979-12-13
Abstract: In a data processing system whose operation is under the control of firmware words stored in a control store, a technique is provided by which a routine which has been temporarily suspended may be returned to. The address of the last instruction executed in such routine prior to such suspension is stored and the routine is returned to by the use of such stored address with one bit thereof changed in state by use of an inverter. The control store is addressed by means of next address generation logic which includes a first multiplexer utilized to address the control store, which multiplexer has several inputs. One of such inputs is received from a latching mechanism which allows more than one test condition to be simultaneously utilized for addressing the control store on a free flow basis. These test conditions, as well as information from an addressed control word, are utilized in a multiplexed arrangement as one input of the first multiplexer. By use of other inputs of such first multiplexer, the control store may be addressed by use of branch address information, as well as other test condition information. A page register provides the page address, to a plurality of pages included in this control store with the locations in each such page addressed by use of the above noted multiplexer combination.

Title: Microprocessor based maintenance system
IPC: G06F11/273
Filed: 1980-09-17
Abstract: Apparatus for use in automated testing of elements in data processing systems such as the central processing unit comprises a microprocessor 10 with associated firmware, RAM 37 and peripheral communications devices. There are two communication interface ports 25 and 26 for receiving commands and instructions from local and remote computer terminals or from data processing units programmed to cause the testing apparatus to perform predetermined sequences of tests. There is also a port for connection to a portable maintenance panel which can be held in the hand of a field engineer for controlling the testing apparatus. The system is designed to replace prior art maintenance panels used for debugging computer hardware. These prior art panels were slow and cumbersome in that data and addresses had to be switched in using numerous toggle switches and data was displayed using numerous LED indicators. Such maintenance panels were also expensive to build. In contrast, the disclosed testing apparatus is relatively inexpensive and allows the field engineers to rapidly perform many tests, thereby minimizing down time. <IMAGE>
