Signal processing method, device and equipment and storage medium

Abstract

The embodiment of the invention discloses a signal processing method, device and equipment and a storage medium, wherein the method is applied to an optical module, and the optical module comprises agolden finger and a register; the register comprises an alarm register and a corresponding shielding register; the golden finger comprises a state pin. The method comprises the steps: obtaining a state of a first flag variable according to an operation of reading a register, wherein the state of the first mark variable represents whether the operation of reading the alarm register is recorded or not; obtaining a state of a second flag variable, wherein the state of the second flag variable represents whether the operation of which the state pin is to be set as the high level is set; judging whether the state of the first mark variable and the state of the second mark variable meet preset conditions or not; under the condition that the state of the first mark variable and the state of the second mark variable meet a preset condition, obtaining the state of a first alarm register and the state of a corresponding first shielding register; and determining the state of the state pin according to the state of the first alarm register and the state of the first shielding register.

Description

technical field [0001] The present invention relates to the technical field of optical modules, in particular to a signal processing method, device, equipment and storage medium. Background technique [0002] At present, a variety of optical module gold fingers contain status pins (INTL pins), such as (Quad Small Form-factor Pluggable, QSFP) optical modules, (Small Form Factor Pluggable, XFP) optical modules, etc. The INTL pins are all abnormal states of optical modules Collective response, if the INTL pin is low, it means that the optical module has abnormal unshielded alarm flags, such as temperature alarms, transmit optical power alarms, voltage alarms, etc. The reason why the INTL pin becomes low can be checked by querying the optical module. The corresponding alarm status register is obtained and cleared (the alarm status of the optical module with the INTL pin is a latched status, and the alarm status is cleared after reading) or masked by the mask register. If the cor...

Problems solved by technology

[0004] The software of the optical module performs other operations except the interrupt processing function, which is usually performed serially in a polling manner. For example, the digital diagnostic monitoring update of the optical module, such as voltage monitoring, temperature monitoring, etc., can only monitor the voltage first, and then monitor the temperature Or monitor the temperature first, and then monitor the voltage. The two cannot be monitored at the same time. The time defined by the optical module protocol is 100ms, and 100ms can be realized by polling, but the release time of the INTL pin is 500us, which is difficult to achieve by polling. If it is implemented by polling, it can only be realized by splitting the function, such as the complete report of the transmitted optical power. Generally, it needs to go through three steps of ADC sampling, calibration, and update of relevant alarm signs. The normal processing method is not to insert in the three-step operation. Any other operations are executed sequentially, but if you want to use the polling method to ensure that the INTL release time is 500us, you may need to split it into three steps, insert the INTL update operation, shorten the single polling time, and ensure that the INTL is released within 500us Pin state update, or use the timer interrupt method to enter the timer interrupt to update the INTL pin state every 500us to ensure that the relevant time definition of the protocol can be met. Both of these methods will increase software complexity and reduce software reliability.
