Title: Program debugging device for microprocessor
Inventor: MIMORI TOSHIMASA
IPC: G06F11/28
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of processing speed of a debugging device by adding an ID to the instruction to be executed by a debugging object processor, referring to the ID change via an external analysis part and then observing the operation of a microprocessor to perform the debugging. SOLUTION: A microprocessor 11 is connected to an analysis part 12 via an ID 13 and an ID strobe 14. An instruction decoding part 18 converts an instruction code 111 outputted from an instruction fetching part 17 into a control signal 112. An instruction execution part 19 outputs a program counter control signal 113 and a microprocessor internal control signal based on the input instructions. The output of both ID 13 and strobe 14 are controlled by the output of an effective ID decision part 10 which decides whether the ID outputted from the part 18 is effective or not. Thus, the ID information is outputted to the outside without adding any debugging instruction nor affecting the original operation of the microprocessor 11. As a result, the debugging jobs are performed at the external part 12.

Abstract: PURPOSE:To output an on/off signal by sensing the change in the contour of a lower arm in response to the motions of closing and opening a palm, and emitting a corresponding electric signal. CONSTITUTION:The arm diameter change sensing part 30 of an arm diameter change sensing switch in a belt form, which is made of an expansive material and in which a sensing element is incorporated, is mounted on a lower arm 32, and an electric signal from the sensing part 30 is fed to a comparison part via a cable 31. When a palm is closed, the arm diameter is thickened, so that the belt fixed to the lower arm 32 elongates. As a result, the contact of the switch opens while the material such as electric wire remains out of elongation, and the resultant resistance value of the sensing part 30 enlarges to cause increase of the divided voltage value to be fed to the (+)-terminal of the comparator, and when the reference value given to the (-)-terminal is exceeded, a signal at a high potential is emitted so that the apparatus concerned is turned on. When the palm is opened, the arm diameter becomes thin, and the belt is restituted to the original length. As a result, the contact of the switch is closed so that the apparatus is turned off.
