Embodiment Construction

[0024] The invention and its various features and advantageous details are explained more fully with reference to exemplary embodiments illustrated in the drawings and detailed in the following description.

[0025] Now refer to the diagram and pay special attention to figure 1 , is shown and generally designated by reference numeral 100 illustrating a diagram of an exemplary asymmetric multi-core processing device (ie, microprocessor or microcontroller) according to various embodiments. In the context of this application, the term "asymmetric" is used to describe two or more cores operating independently. The processor core may be the same, but operate from different memory and, if a microcontroller implementation, with different peripherals. According to other embodiments, two different cores may be implemented or two identical cores may be implemented running with different system clocks. However, the principles of the present application are not limited to such implemen...

Abstract

The invention discloses a system and method for generating cross-core breakpoints in a multi-core microcontroller. In a debugging method for an integrated circuit device which has multiple processing cores, a debugging breakpoint is activated at a first processor core in the integrated circuit device. Upon activation, the debugging breakpoint stops execution of instructions in the first processor core and the debugging breakpoint is communicated to a second processor core in the integrated circuit device.

Description

[0001] Related patent applications [0002] This application claims priority to commonly owned U.S. Provisional Patent Application No. 62 / 112,552, filed February 5, 2015, which is hereby incorporated by reference for all purposes middle. technical field [0003] The present invention relates to processors, and in particular to systems and methods for generating cross-core breakpoints in multi-core processors, in particular asymmetric multi-core processors. Background technique [0004] A processor breakpoint is a stop, also known as a pause, in a program placed at an appropriate location for debugging purposes. Processor breakpoints are typically triggered when specific memory locations are accessed. During an interrupt, the memory, registers, etc. environment is checked to determine if the program is functioning as expected. The memory location can be in program memory and can include specific instructions that, when fetched by the processor, can trigger a breakpoint an...
