<p>PURPOSE:To make small the processor with a simple circuit constitution, by applying the lower rank of data of a program memory to the address of a temporary storage directly, executing the program even during the reset period and constituting the reset circuit while keeping the input of the temporary storage to zero. CONSTITUTION:An initial reset signal is given to an initial reset terminal 30, then a storage circuit 2 is reset and output terminals 29a-29c are all kept at zero. Further, the output of an oscillator 1 is fed to a program counter 2, which keeps advancing even during the initial reset period. A program memory 3 outputs instructions to data lines 5a-5d sequentially. Further, during the initial reset period, the data input terminal 12 of a temporary storage memory is kept zero to write in zero to all the areas of the temporary storage memory used in the program in a memory 3. By releasing the initial reset signal after that, the operational processor starts a normal operation.</p> |
