Embodiment Construction

[0013] The present invention will be described in further detail below through specific examples. The following examples are only descriptive and non-restrictive, and cannot limit the protection scope of the present invention with this.

[0014] The method for interactively debugging the parameters of the memory controller of the Loongson processor of the present invention mainly modifies the contents of the registers of the Loongson memory controller according to the register index value of the Loongson memory controller. The register index of the memory controller refers to the address offset of the memory controller register in the memory controller. For example, the first register index value is 0, the second is 1, and so on. The Godson memory controller contains a total of 180 register; the register content of the memory controller refers to an 8-byte hexadecimal constant value.

Abstract

The invention discloses a method for interactively debugging parameters of an internal memory controller of a Loongson processor. The method comprises the following steps of S1, loading basic internal memory configuration parameters; S2, judging whether to carry out internal memory training, if so, executing the step S3, and otherwise, directly jumping to the step S4; S3, carrying out the internal memory training; S4, judging whether the internal memory configuration parameters need to be corrected, and if the internal memory configuration parameters do not need to be continuously corrected, jumping to the step S7; S5, reading to-be-corrected register index values and register contents of the internal memory controller, and storing the register index values and the register contents into the internal memory controller of the processor; S6, jumping to the step S4; S7, storing the corrected contents of the internal memory controller into a flash memory.

Description

technical field [0001] The invention belongs to the technical field of Loongson processors, and in particular relates to a debugging method for memory controllers of Loongson processors. Background technique [0002] With the gradual improvement of the performance and stability of Loongson processors and the country's promotion and support for localization, computers based on Loongson processors began to be popularized and applied in various industries. Since the structure of the Loongson processor is different from that of the commercial X86 processor, the processor integrates a memory controller, and the stability and performance of the memory controller greatly affect the performance stability of the computer. When the processor on the computer motherboard When the layout of memory slots changes or the computer application environment changes, in order to ensure the efficient and stable operation of the whole machine, the configuration parameters of the memory controller ...
