Circuitry 112 further includes one or more sensors 312 coupled to MCU 334. Further, circuitry 112 further includes a microphone 314 coupled to DSP 330 via an analog-to-digital converter (ADC) 316. Circuitry 112 may also include a range finder circuit (not shown), such as a laser range finder or other range finder circuit, that may be coupled to one of the FPGA 320 and the image processing circuit 306 and that may cooperate with sensors 312 to receive reflected data that can be used to determine the range to a target. DSP 330 and MCU 334 are coupled to FPGA 320.
Sensors 312 are configured to measure one or more environmental parameters (such as wind speed and direction, humidity, temperature, and other environmental parameters) and/or to measure optical elements, such as reflected laser range finding data, and to provide the measurement data to MCU 334. Circuitry 112 can further include a microphone 314 to capture sounds and to convert the sounds into an electrical signal, which it can provide to ADC 316, which may include an output coupled to an input of DSP 330. In some embodiments, the microphone 314 may be external to circuitry 112, and circuitry 112 may instead include an audio input jack or interface for receiving an electrical signal from microphone 314.

In a particular example, transceiver 310 is a wireless transceiver for communicating data to and receiving data from computing device 108. In an embodiment, transceiver 310 communicates with computing device 108 to establish a communication link, receives a software module or a set of instructions related to a software module and stores the instructions one of memory 332, 336, and 322, depending on which of the DSP, 330, MCU 334, and FPGA 320 will be executing the instructions to provide a particular function.
Network transceiver 328 can communicate with network 106 to retrieve a selected software module from application store 104. In an example, a zoom upgrade software module 126 may be installed in memory 322 for execution by FPGA 320, in memory 332 for execution by DSP 330, and/or in memory 336 for execution by MCU 334 to process video data from optical sensors 318 to provide enhanced zoom functionality.

MCU 334 processes instructions and settings data stored in memory 336 and is configured to control operation of circuitry 112. FPGA 320 is configured to process image data from image (optical) sensors 318. FPGA 320 processes the image data to enhance image quality through digital focusing and gain control. Further, FPGA 320 can perform image registration and stabilization. FPGA 320 may cooperate with DSP 330 to perform optical target tracking within the view area of the portable optical device that incorporates circuitry 112. FPGA 320 further cooperates with MCU 334 to mix the video data with overlay data, such reticle information and target tracking information (from DSP 330) and provides the resulting image data to display 324. As a target moves within the view area, DSP 330 can perform target tracking and can apply a visual marker to the target shown on display 324. The FPGA 320, DSP 330 and MCU 334 can cooperate to modify a portion of the media content sent to display 324 based on signals received from computing device 108 and/or from network 106. In particular, any functionality or capability provided by optical device 110 may be upgraded, adjusted, or added through installation of a selected software module.
