Processors

Among various factors that go into processor selection, a few critical are performance, power consumption, memory, cost per unit and ease of upgrade. At Intelligraphics we keep in mind these parameters to select most suitable processor for any product.

Processor selection for power starved devices: While designing battery operated devices (with time between battery charging of 2-4 days) we have chosen processors that require minimum power and small form-factors. These are primarily used in logistics management, location identification and asset tracking applications. Typical processors include Microchip PIC18 and PIC24 series.

Processor selection for industrial applications: Selection of processors from a range of 8-bit to 32-bit processors depends on considerations such as continuous power, 24 x 7 operations in rugged environment, built-in ADCs, requirements of math co-processor for PID algorithms and connectivity options such as RS485, Ethernet and RF. Typical applications include universal DIO controllers, data loggers, chiller controllers, DDC and protocol converters. Typically Microchip PIC24 and NXP LPC series are used.

Processor selection for high end devices: 32-bit processors are used for different requirements such as support for video cameras (hardware based real-time compression and decompression), streaming applications, Wi-Fi, storage requirements, HMI displays and small form-factors. Dual core processors with DSP and ARM core are used extensively for such applications. Applications like bus consoles with cameras, video based security surveillance systems, Wireless DVR solutions are developed using Texas Instrument’s DM365, and DM368, OMAP series and NXP LPC series.
