Problems solved by technology

[0004] In summary, the boot mode configuration pins will be occupied when the system starts, and the boot mode configuration pins will no longer be used after the system starts, but the prior art does not have a solution to reduce the number of chip boot mode configuration pins. Therefore, the boot mode When the number of configuration pins is large, it will occupy a large board area and increase the difficulty of wiring

Embodiment 1

[0032] see figure 2 , this embodiment provides a method for configuring a chip, including:

[0033] 101: Configure the function mode of the chip in the non-volatile memory of the chip, and the function mode includes at least a startup mode;

[0034] 102: Send the function mode in the non-volatile memory to other functional modules in the chip except the non-volatile memory.

[0035] Specifically, step 102 includes: resetting other functional modules, reading the functional modes from the non-volatile memory, and decoding them; sending the decoded functional modes to corresponding other functional modules, and decoding the other functional modules reset.

[0036] In the method provided by this embodiment, by configuring the functional mode of the chip in the non-volatile memory, and sending the functional mode in the non-volatile memory to other functional modules except the non-volatile memory, when the functional mode is started In the mode, there is no need to start the ...

Embodiment 2

[0038] see image 3 , this embodiment provides a method for configuring a chip, including:

[0039] 201: Configure the function mode of the chip in the non-volatile memory of the chip, the function mode at least includes a startup mode;

[0040] Specifically, the functional mode can be programmed through ATE vectors, board-level programming logic, etc., and the programmed functional mode can be programmed into the non-volatile memory. Wherein, the non-volatile memory refers to a memory whose data will not be lost when the chip is powered off, and includes OTP (One Time Programmable, one-time programmable) memory and MTP (Multi Time Programmable, multiple times programmable) memory. Chips include SOC (System On a Chip, system-on-a-chip) or non-SOC.

[0041] Wherein, the startup mode includes the startup mode type and its parameter description. For example, see Table 1 and Table 2, the boot mode types include off-chip Nand Flash boot, non-secure E 2 PROM (Electrically Erasab...

[0066] The configuration module 301 is configured to configure the function mode of the chip in the non-volatile memory of the chip, and the function mode includes at least a start-up mode;

[0067] Among them, the function mode can be programmed through ATE vector, board-level programming logic, etc., and the programmed function mode can be programmed into the non-volatile memory. The non-volatile memory refers to the memory whose data will not be lost when the chip is powered off, and it includes OTP (One Time Programmable, one-time programmable) memory and MTP (Multi Time Programmable, multiple times programmable) memory. Chips include SOC (System On a Chip, system-on-a-chip) or non-SOC.

[0068] Wherein, other functional modules include but not limited to a CPU (Central Processing Unit, central processing unit), and a Memory (memory) controller.

[0069] The sending module 302 is configured to send th...

Abstract

The invention discloses a method and a device for configuring a chip, and belongs to the field of chips. The method comprises the following steps: configuring a function mode of the chip in a nonvolatile memory of the chip, wherein the function mode at least comprises a start-up mode; and sending the function mode in the nonvolatile memory to other function modules except the nonvolatile memory. The device comprises a configuration module and a sending module. Through the method, start-up mode configuring pins are not needed, and the total number of the pins is reduced, so the area of a single board is decreased, the wiring difficulty and chip cost are reduced and the design of the single board is simplified.

Description

technical field [0001] The invention relates to the field of chips, in particular to a method and device for configuring chips. Background technique [0002] During the start-up process of the chip, the internal functional modules need to be configured, and the content related to the start-up mode is loaded into the chip. [0003] The method of configuring the chip in the prior art is as follows: specific hardware configures the boot mode into the chip through pins of the chip. Here, the pins used for booting are called boot mode configuration pins. For example, E2PROM (Electrically Erasable Programmable Read-Only Memory, Electrically Erasable Programmable Read-Only Memory), Nand Flash and other hardware configure the boot mode into the chip through the corresponding boot mode configuration pins. The startup mode generally includes multiple startup mode types, and each startup mode type includes multiple parameter descriptions. Therefore, pins are required to distinguish th...
