Abstract:
1. A temperature adaptive circuit comprising: a circuit that selectively performs, based on an instruction, an ordinary operation, which is an operation in a temperature range where a normal operation is possible, or a temperature rise operation, which is an operation of raising its temperature; and a motion control section that outputs an instruction for either of said ordinary operation and said temperature rise operation to said circuit; wherein said circuit includes: a pattern generation section that generates a data pattern for said temperature rise operation; a selector that is input with said data pattern output by said pattern generation section as a first input, and with a data pattern for said ordinary operation input thereto from the outside as a second input, so that said first input and said second input are switched from each other in accordance with an instruction from the outside; a switching control section that switches said selector in accordance with an instruction from said motion control section; a scanning chain that operates a plurality of flip flops based on an output of said selector; and a temperature measuring section that measures the temperature of said circuit, and outputs it to said motion control section; wherein said pattern generation section outputs data pattern, in which a bit is inverted once per two bits, in response to an output of said scan chain.
