Introduction

KPT45526-261 is one of the most advanced digital signal processing (DSP) devices available in the market. It is an excellent choice for applications requiring high speed processing such as digital audio and video, medical imaging, and embedded systems. The KPT45526-261 architecture is optimized for high speed computation and provides various system capabilities flexibility. It features two 200MHz CoreFusion™ Processors with dual DDR3 SDRAM memory interfaces, one Quad SPI NAND flash memory interface, 32KB I/O ports, interfaces to various communication protocols and low power operation.

Application Field

The KPT45526-261 is ideal for applications requiring high speed processing, where a combination of Video, Graphics, Audio and Control functions are needed. These include automotive infotainment systems, digital television, industrial automation, home security systems, medical imaging, telecommunication systems, multimedia gaming, video surveillance, traffic control systems, and many other embedded applications. It is capable of supporting multiple operating systems such as Windows, Linux, and Android. In addition, the KPT45526-261 contains many built-in peripherals to further enhance its performance such as USB, Ethernet, and Serial Interfaces.

Working Principle

The KPT45526-261 integrates two 200MHz CoreFusion™ Processors and a dedicated 512KB of Level 3 Cache memory. Both processors share the same Fourth Level (Level 4) Cache, both of which work in concert to execute instructions quickly. Each processor has two DDR3 SDRAM memory interfaces, so that memory is quickly accessible. One of the Quad SPI NAND Memory interfaces provides the flexibility to expand the internal storage of the system. In addition, the onboard 32KB I/O ports allow for external connections with sensors, motor drive, and other external devices.

The KPT45526-261 supports numerous proprietary and industry communications protocols such as CAN, USB, Ethernet, and Serial. It is fully integrated with an on-chip peripheral controller that handles all the complicated timing and protocol handshakes needed by the communication protocol. In addition, several DMA (Direct Memory Access) channels are integrated to offload the CPU from memory copy duties, such as moving data from one memory location to another.

The KPT45526-261 contains additional features that provide further flexibility and added functionality. These include power control logic, flash memory controllers, real time clock, and watchdog timer. Power control logic can provide more efficient power management, while the flash memory controllers allow for faster data transactions. The real time clock ensures that the time-dependent software functions are always executed properly, while the watchdog timer provides an added layer of security.

Conclusion

The KPT45526-261 is an ideal choice for applications requiring high speed processing with multiple operating systems, versatile communication protocols, and embedded functionality. Its advanced architecture enables fast instruction execution and optimized system performance. The onboard peripherals, power control logic, flash memory controllers, and real time clock provide additional system capabilities and improved application efficiency. With these features, the KPT45526-261 is the perfect solution for many of today\'s demanding embedded applications.
