Problems solved by technology

However, as a result of connecting multiple processors to the integrated peripheral control LSI, a large number of I / O pins are required on the peripheral control LSI
If the number of I / O pins exceeds the number that can be accommodated in the envisaged package of the peripheral control LSI, it will be difficult to realize the integration of the peripheral control LSI (see figure 2 )

Embodiment Construction

[0017] For processors connected on an integrated peripheral control LSI, multi-core technology has been applied in recent years, enabling processing to be performed with a plurality of cores configured in one processor. The present invention realizes the integration of peripheral control LSIs by applying the above-mentioned multi-core processor technology to the framework of a numerical control device for controlling machine tools or industrial machines. That is, by distributing and executing the numerically controlled function and the PMC controlled function that have been performed separately in different processors to multiple cores of the multi-core processor, the functions of the numerically controlled function block and the PMC controlled function block are realized. The integration of each required peripheral control LSI.

Abstract

A numerical controller includes a multicore processor, an integrated peripheral control LSI, a motor control section and an amplifier interface section. The multicore processor has two cores. One is assigned as a numerical control section processor core, and the other is assigned as a programmable machine controller section processor core. The motor control section is composed of a motor control section processor and a peripheral control LSI.
