**ADSP-21062KSZ-160: A High-Performance SHARC DSP for Demanding Embedded Signal Processing Applications**
In the realm of embedded digital signal processing, where real-time performance, precision, and reliability are paramount, the **ADSP-21062KSZ-160** stands out as a formidable solution. As a member of Analog Devices' renowned **Super Harvard Architecture (SHARC)** family, this processor is engineered to tackle the most computationally intensive tasks across a diverse range of applications, from professional audio and medical imaging to industrial control and defense systems.
At the heart of the ADSP-21062KSZ-160 is a **32-bit floating-point computational core** capable of executing a single-cycle multiply-accumulate (MAC) operation. This is crucial for the complex matrix operations and high-order filter calculations common in advanced algorithms. The '160' suffix denotes its **160 MHz core clock speed**, enabling it to deliver a peak performance of **480 MFLOPS (Million Floating-Point Operations Per Second)**. This raw processing power ensures that even the most demanding real-time signal processing workloads can be handled with significant headroom.
A key differentiator of the SHARC architecture is its sophisticated multi-bus structure. The processor features separate program and data memory buses, complemented by an I/O controller bus. This design effectively eliminates the von Neumann bottleneck, allowing for the simultaneous fetch of an instruction, two operands, and a DMA transfer. The chip integrates a substantial **4 megabits of on-chip dual-ported SRAM**, which can be configured as both program and data memory. This large internal memory block is essential for maintaining high processing speeds by minimizing wait states and costly delays associated with accessing external, slower memory.
For expanding the system's capabilities, the ADSP-21062KSZ-160 is equipped with a comprehensive set of **integrated peripherals**. These include serial ports, a timer, and a powerful **DMA (Direct Memory Access) controller** that operates independently of the core. The DMA controller is vital for efficient data flow, allowing the processor core to focus on computation while the peripherals seamlessly move data to and from memory. Furthermore, its **support for glueless multiprocessing** is a standout feature. Through its shared bus connectivity and distributed bus arbitration logic, multiple ADSP-21062 processors can be linked together to form a high-performance, scalable multiprocessing system, dramatically increasing aggregate processing power for the largest challenges.
Designed for robustness in harsh environments, this DSP is available in an industrial temperature range grade, making it suitable for applications that must operate reliably under extreme conditions.
