<p>A digital apparatus for controlling an operation of an electric motor capable of realizing a fully digital speed control without creating a severe restriction on data transfer and an excessive demand on the micro-processor 1. The apparatus includes a micro-processor 1 for carrying out normal speed control processings at normal speed timings; a high speed digital processor 5, 6, 7 for carrying out high speed control processings at high speed timings faster than the normal speed timings; an interface register (25, 27, 31 Fig 3) for interfacing data transmission between the micro-processor and the high speed digital processor; and a timing circuit (18) for receiving access signals from the micro-processor, and producing timing signals based on the high speed timings by using the access signals where the timing signals control timings of the data transmission through the interface register. <IMAGE></p> |
