The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Example 1
As shown in fig. 4, a mobile phone signal testing system based on dual-core communication includes an upper computer, a baseband signal processing module and a radio frequency carrier module.
And the upper computer issues corresponding control instructions through configured software to realize the control of the working mode and the receiving and transmitting control of the hardware equipment.
The baseband signal processing module is in communication connection with the upper computer, and in one implementation manner of the embodiment, the baseband signal processing module comprises a USB3.0 port, and the baseband signal processing module is connected with the upper computer software through the USB3.0 port so as to receive a control instruction issued by the upper computer software.
Further, referring to fig. 5, the baseband signal processing module adopts a ZYNQ dual-core processor; in the implementation process, the ZYNQ dual-core processor can select a ZYNQ-7000AP Soc chip, and the dual-core Cortex-A9ARM core and the FPGA are integrated into one chip to form a fully programmable chip.
Illustratively, the ZYNQ dual-core processor is internally divided into an APU-based processing system PS (Processing System) and an FPGA-based programmable logic PL (Programmable Logic). The design is to perform program migration on a dual-core processor, so that the PS part is mainly used. The PS part mainly comprises the following functional modules: the application processing units APU, shared memory OCM, etc. are not described in detail herein. The APU is an operation unit in the PS part, and the main part is two Cortex-A9ARM processors, comprising a main core CPU0 and a secondary core CPU1, wherein the secondary operating system is controlled to be started and closed by the secondary operating system in the form of remote firmware running on the main system by adopting a starting mode guided by the main core.
In the implementation process, the ZYNQ dual-core processor establishes connection between a programmable logic PL part of a baseband signal processing module and a peripheral hardware module through a BRIDGE (AXI_MIF_BRIDGE) to form a processor hardware foundation; the peripheral hardware module includes an analog-to-digital converter and a digital-to-analog converter. It should be noted that a shared memory OCM may enable low latency and high throughput data exchange, and OCM typically has faster access speeds and lower power consumption than external storage, such as external RAM. By storing the data in the shared memory OCM, the respective Cortex-A9ARM processor can quickly read and write the data without additional overhead such as a cache coherency protocol.

Further, in order to avoid read collision of the double-check shared memory OCM, the dual-core communication module of the ZYNQ dual-core processor communicates based on an interrupt communication mechanism; the sender generates a software interrupt by writing an SGI interrupt number into the ICDSGIR register and designating a target core in the communication process, and the receiver reads the memory after receiving the interrupt and writes 1 clear interrupt into the corresponding position of the ICDSGIR register, thereby implementing C program jump and exclusive access of the peripheral through the shared memory OCM and the soft interrupt, and detailed description is made later on in the specific C program jump control flow;
the mobile phone signal testing method based on dual-core communication, as shown in fig. 1, specifically comprises the following steps:

For example, referring to fig. 2, the configuration of the receiving link of the radio frequency carrier module into the master core, the configuration of the transmitting link control into the slave core, and waking up the master core to perform the receiving link control include:
the main core extracts the rest information except the frame header, namely configuration parameter information, from the upper computer instruction, performs peripheral configuration based on the configuration parameter information, and waits for a start command; when a start command is received, sending a receiving link interrupt to a slave core, and waiting for a sampling signal trigger; and after the baseband signal processing module finishes sampling, ending interruption to the slave core transmission.
For example, referring to fig. 2 and 3, when the upper computer instruction relates to transmission link control, disabling the authority of the master core to access the upper computer interface, granting the authority of the slave core to access the upper computer interface, sending a transmission link interrupt to the slave core, and waiting for completion of the interrupt from the slave core; and when receiving the interrupt transmitted from the slave core, releasing the authority of the master core to access the upper computer interface.
Specifically, waking up the slave core for transmission link control includes: when receiving a transmission link interrupt transmitted by a main core, the auxiliary core extracts configuration parameter information from an upper computer instruction, performs peripheral configuration based on the configuration parameter information, and waits for a start command; when a start command is received, a test waveform signal is sent to the baseband signal processing module, and the peripheral access authority of the slave core is deactivated; an end interrupt is sent to the master core.
Further, the upper computer instruction further relates to a transmit-receive link simultaneous operation control, and for the transmit-receive link simultaneous operation control, the master core and the slave core still adopt a starting mode guided by the master core, the master core performs the receive link control preferentially, and the slave core performs the transmit link control, and the specific flow is as follows:
the main core is awakened, configuration parameter information is extracted from an upper computer instruction by the main core, a receiving link control flow is executed based on a part related to receiving link control in the configuration parameter information, and a part related to transmitting link control in the configuration parameter information is stored in an OCM; and waking up the slave core, wherein the slave core acquires configuration parameter information from an OCM or an upper computer interface, and executes a transmission link control flow based on the configuration parameter information.
If the OCM or the upper computer interface has no data, the peripheral access authority of the slave core is deactivated after the ending interrupt sent by the master core is received, and the ending interrupt is sent to the master core.
In addition, for the case that the upper computer instruction does not include the receiving link control nor the transmitting link control, corresponding control operations, such as functions of reading and writing calibration flash, updating firmware, and the like, are performed in the main core, and redundant description is not made here.
