Abstract
The invention discloses an SOC (System On Chip), which comprises a microcontroller, a storage direct access module, a memory management unit, a watchdog, a timer, a system controller, a peripheral interface and a plurality of function modules, which are respectively connected with a bus, wherein the SOC also comprises a one time programmable storage; the one time programmable storage is connected with the microcontroller. The SOC can be directly secondly developed and upgraded without changing and utilizing other external devices, does not need an external code, and is simple in structure, and convenient and quick to upgrade.
Description
Technical field
The present invention relates to integrated circuit fields, relate more specifically to a kind of SOC.
Background technology
Please refer to Fig. 1, Fig. 1 is the SOC of prior art.As shown in the figure, existing SOC comprise be connected with bus respectively microcontroller, direct memory access (DMA) module, memory management unit, house dog, timer, system controller, Peripheral Interface and multiple functional module, wherein also comprise the ROM be connected with described microcontroller.The firmware stored in described microcontroller access ROM also runs this firmware, and by each functional module such as data bus, the direct access modules of control bus config memory, memory management unit, house dog, timer, system controller, Peripheral Interface, cooperatively interact with microcontroller thus realize the specific function of multiple functional module.
But setting is perfect before the firmware of the SOC of prior art must throw sheet, follow-up have need newly-increased function just can only be upgraded by external code, then probably cannot carry out function upgrading, affect secondary development.
Therefore, be necessary to provide the SOC of improvement to overcome above-mentioned defect.
Summary of the invention
The object of this invention is to provide a kind of SOC, SOC of the present invention does not need to change and utilize other device outside directly can carry out secondary development and upgrading, and without the need to external code, structure is simple, upgrading fast and easy.
For achieving the above object, the invention provides a kind of SOC, comprise be connected with bus respectively microcontroller, direct memory access (DMA) module, memory management unit, house dog, timer, system controller, Peripheral Interface and multiple functional module, wherein, described SOC also comprises disposable programmable memory, and described disposable programmable memory is connected with described microcontroller.
Preferably, described bus comprises data bus and control bus, and described data bus, control bus are connected with microcontroller, direct memory access (DMA) module, memory management unit, house dog, timer, system controller, Peripheral Interface and multiple functional module respectively.
Preferably, described Peripheral Interface can be SPI interface, I2C interface, USB interface, GPIO interface, UART interface and ddr interface.
Compared with prior art, SOC of the present invention is owing to also comprising disposable programmable memory, when SOC of the present invention is upgraded or secondary development time, only need the upgrading that can realize in the firmware burning designed to disposable programmable memory SOC or secondary development, and without the need to external code in escalation process; Structure is simple, upgrading fast and easy.
By following description also by reference to the accompanying drawings, the present invention will become more clear, and these accompanying drawings are for explaining the present invention.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the SOC of prior art.
Fig. 2 is SOC structured flowchart of the present invention.
Embodiment
With reference now to accompanying drawing, describe embodiments of the invention, element numbers similar in accompanying drawing represents similar element.As mentioned above, the invention provides a kind of SOC, SOC of the present invention does not need to change and utilize other device outside directly can carry out secondary development and upgrading, and without the need to external code, structure is simple, upgrading fast and easy.
As shown in Figure 2, SOC, comprise be connected with bus respectively microcontroller, direct memory access (DMA) module, memory management unit, house dog, timer, system controller, Peripheral Interface and multiple functional module, and described microcontroller is also connected with a disposable programmable memory; Described microcontroller is accessed the firmware of storage in described disposable programmable memory and is run this firmware, thus realizes the specific function of multiple functional module by the direct access modules of bus driver, memory management unit, house dog, timer, system controller, Peripheral Interface and many directly access modules, memory management unit, house dog, timer, system controller, Peripheral Interface and multiple functional module and cooperatively interacting of microcontroller.SOC of the present invention, when SOC is upgraded or secondary development time, only need the upgrading that can realize in the firmware burning designed to disposable programmable memory SOC or secondary development, and without the need to external code in escalation process; Structure is simple, upgrading fast and easy.Such as: SOC of the present invention is only designed to the electronic business card of a low side at the beginning; When chip production out after, wish again to utilize this chip directly to do card reader, now only need redesign the firmware (utilize GPIO analog card interface) corresponding with card reader, be burnt in described disposable programmable memory.In addition, the specific works process of described SOC and principle are well known to the skilled person, and no longer carefully state at this.
Refer again to Fig. 2, as the preferred embodiment of the present invention, described bus comprises data bus and control bus, and described data bus, control bus are connected with microcontroller, direct memory access (DMA) module, memory management unit, house dog, timer, system controller, Peripheral Interface and multiple functional module respectively; The data message of each device of described data bus transmission, described control bus is in order to transmit the control signal of each device.In addition, described Peripheral Interface can be SPI interface, I2C interface, USB interface, GPIO interface, UART interface and ddr interface; Certainly as the preferred embodiment of the present invention, described Peripheral Interface is not limited to above-mentioned interface, physical interface can according to the interface of external devices relative set.
More than in conjunction with most preferred embodiment, invention has been described, but the present invention is not limited to the embodiment of above announcement, and should contain various carry out according to essence of the present invention amendment, equivalent combinations.
