Abstract: Disclosed are a matrix track system, a production line with associated loops and a production method using the production line. The matrix track system includes a plurality of track nodes which are arranged in a matrix and a plurality of fixed guide rails connecting the track nodes. The fixed guide rails include a plurality of longitudinal guide rails and a plurality of transverse guide rails. Each of the track nodes includes a turnout mechanism which includes a straight guide rail, an arc guide rail and a switch component for the switching of the straight guide rail and the arc guide rail.

Abstract: An information protection method and device based on a plurality of sub-areas for an MCU chip, the MCU chip comprises an instruction bus, a data bus, a flash controller and a user area of a flash memory, the method comprises: determining a preceding sub-area when the instruction bus accesses the user area; entering corresponding preceding sub-area working state; determining the current sub-area when the instruction bus accesses the user area; when the preceding sub-area is inconsistent with the current sub-area, entering the transition state; determining whether the duration of the transition state reaches the preset waiting time; if yes, entering the corresponding current sub-area working state. The information protection method and device prevent the cooperative companies which develop the program together from stealing program from each other.

Abstract: A flash controller and a control method for the flash controller. The flash controller comprises an instruction bus interface, a data bus interface, a configuration register, an erase access filter module, a read/write access filter module and a flash control module. The read/write access filter module is configured to receive control information and determine whether the read/write access is sent to the flash control module or not. The erase access filter module is configured to receive control information and determine whether the erase access is sent to the flash control module or not. The flash control module is configured to complete an access to a flash memory. The present disclosure is used to protect programs from being stolen by a client, and also protect against a situation where companies collaboratively developing a program are able to steal programs from one another.

Abstract: The disclosure discloses a method and a device of information protection for a micro control unit (MCU) chip, the MCU chip comprises an instruction bus, a data bus, a flash controller and a user area of a flash memory; the flash controller is used to divide the user area into a first sub-area and a second sub-area; the method comprising: when the instruction bus accesses the user area, determining, whether the instruction bus accesses the first sub-area; if yes, entering the first sub-area working state; in the first sub-area working state, if the instruction bus accesses the second sub-area, entering the transition state; determining whether the time at transition state reaches a preset waiting time; if yes, entering the second sub-area working state; the disclosure is used to protect program from being stolen by users and prevent the cooperative companies stealing program from each other.

Abstract: An embedded system controller comprises a main chip and a flash memory. The main chip comprises: a bus; a random access memory; and a storage control module which is configured to copy program data to be used to the random access memory from the flash memory, and also configured to read required program data from the random access memory when receiving a read access request from the bus and write program data to be written into the random access memory and the flash memory when receiving a write access request from the bus. The present application can allow the main chip of an embedded system controller to be manufactured using an advanced standard circuit manufacturing process and achieve excellent performance and power consumption.
