The Microprocessors that Benefit Avionics Systems
Microprocessors are a type of computer processor where all logic and control elements are situated onto a single integrated circuit. Assisting in the overall functionality of the central processing unit of a computer or device, the microprocessor executes and contains all necessary arithmetic, control circuitry, and logic. Within military aerospace applications, flight and mission control systems undergo intensive operations that necessitate a high amount of processing power to properly be carried out. In this blog, we will discuss microprocessors in relation to avionic systems, allowing you to better understand the role that they serve.
When using processor components that are capable of operating over a large temperature range, one can achieve high optimization of data-link resources, ensuring that response times are rapid for the ease of management. For many flight computers, the PC7448 processor is quite popular, coming in the form of a superscalar microprocessor with 3000 Dhrystone MIPS performance. Additionally, the processor also has integrated L1 and L2 cache coupled with multicore processors. While such processors typically exhibit a service life ranging from 10 to 15 years on average, some manufacturers offer deals to ensure that parts can quickly be replaced as needed to extend service lives even further.
For aircraft engine systems, the PC5674 is a more recent processor that operates on a temperature range of -55°C to 150°C to optimally function in such an extreme environment with thermal protection. For its capabilities, the PC5674 can manage engine control, provide users a programmable timer interface, take advantage of its 12-bit analog-to-digital converter, and more. Additionally, the unit contains embedded flash program storage and SRAM for functionality.
Communication control often requires intensive processing, and thus processors such as the PC8548E and the P2041 are optimal choices. This is due to the fact that both processors feature a DDR memory interface and Ethernet, PCIe, and GPIO capabilities. Additionally, their encryption engines are quite powerful, aiding in various algorithms. Advanced encryption is very useful for certain applications, especially those that are related to military-grade hardware.
Alongside aerospace applications, powerful microprocessor components also find use in space applications. As space systems continue to advance, manufacturers have sought out microprocessor technology for satellites that can surpass conventional radiation hardened microelectronic devices. Freescale microprocessors may be a suitable candidate, featuring an inherent radiation tolerance. The PC7448 and PC8548 are two components that may find use in such applications, their clock speeds surpassing 1GHz and their assemblies containing advanced processing engines. With the use of such processing hardware, intensive onboard data processing can be undertaken for the means of improving the overall efficiency of satellites.
As microprocessors continue to become improved with more capabilities and features, such devices may further find use in a variety of aviation, defense, and space applications. When purchasing a microprocessor, one should always conduct necessary research to ensure that the device they wish to procure is compatible with the application in question and meets all necessary requirements for functionality.
