Introduction to Analog Devices ADSP-21060CZ-160 SHARC Processor

The Analog Devices ADSP-21060CZ-160 SHARC processor stands out as a high-performance, 32-bit embedded signal processing microcomputer. Designed to handle demanding applications in communications, graphics, and advanced imaging, this member of the SHARC (Super Harvard Architecture Computer) family features a robust architectural foundation and a comprehensive system-on-chip integration. With a 40 MHz clock rate delivering up to 40 MIPS and a 25 ns instruction cycle time, the ADSP-21060CZ-160 targets real-time, throughput-intensive environments in control systems, radar, and digital audio processing.

Offering single-cycle instruction execution and a broad range of computation features, the ADSP-21060CZ-160 SHARC is ideal for engineers and procurement professionals seeking DSP solutions capable of direct interfacing to both external memory and processors. Its packaging in a 240-lead CQFP format ensures suitability for surface-mount designs and rugged deployment scenarios with operating temperatures from -40°C to 100°C.

Key functionalities and digital signal processing design of ADSP-21060CZ-160

The ADSP-21060CZ-160 SHARC processor builds on the proven performance of the ADSP-21000 DSP core, integrating three parallel 32-bit IEEE floating-point computation units: an arithmetic/logic unit (ALU), a multiplier, and a shifter. These units each deliver single-cycle instructions and can execute multiply-and-add operations crucial for DSP algorithms such as FFTs and digital filtering. This parallelism achieves up to 120 MFLOPS peak and 80 MFLOPS sustained throughput, supporting complex mathematical processing in real-time environments.

A unique aspect of the architecture is the Super Harvard design, granting the processor four independent buses that allow simultaneous dual data fetches, instruction fetches, and nonintrusive I/O traffic. Engineers benefit from dual data address generators (DAGs) featuring hardware circular buffer support, optimizing data flow and reducing overhead for common signal processing operations. The selective on-chip instruction cache enables three-bus operation, maximizing efficiency in looped and cache-optimized routines.

Flexible program sequencing is achieved through zero-overhead looping, single-cycle loop setup, and an efficient instruction set that supports parallel execution of conditional multiplies, adds, subtracts, and branching. The ADSP-21060CZ-160 enables simultaneous fetching of instruction and two operands—facilitating high-throughput operation in DSP-centric workloads.

On-chip memory, input/output, and system integration features of ADSP-21060CZ-160

A central advantage of the ADSP-21060CZ-160 SHARC processor is its substantial embedded dual-ported SRAM, providing 4M bits configured in two equal memory blocks. Each block supports flexible combinations of 16-, 32-, and 48-bit word sizes, with support for fixed- and floating-point formats to maximize storage efficiency. Dual-ported architecture enables single-cycle, independent access by both core processor and I/O peripherals or DMA controllers—crucial for latency-sensitive signal and control processing.

System integration is furthered by the processor’s extensive I/O capabilities. A built-in host interface supports direct connection to 16- or 32-bit external microprocessor buses with asynchronous transfers at full processor speeds, minimizing hardware complexity for integration with legacy or custom controllers. Four DMA channels handle rapid code and data movements between host processors and internal memory.

High-speed off-chip memory interfacing includes support for DRAM and parallel bus architectures, with programmable wait states and bank control signals. Additional connectivity is delivered by six link ports designed for point-to-point interprocessor communication at rates up to 240 MBps, making the ADSP-21060CZ-160 a solid choice for distributed and array multiprocessing systems. Dual synchronous serial ports (two at 40 Mbps) with built-in companding hardware extend peripheral integration—ideal for multi-channel audio and sensor applications.

Parallel processing and scalability solutions using ADSP-21060CZ-160

The ADSP-21060CZ-160 SHARC processor is engineered for scalable multiprocessing—an essential attribute for modern signal processing networks and multi-DSP platforms. A unified address space and distributed bus arbitration logic enable simple, glueless connectivity of up to six ADSP-21060CZ-160 processors plus a host, supporting both fixed and rotating bus arbitration for flexible system architectures. Master processor handover and vector interrupts facilitate efficient interprocessor communication and control.

The multiprocessor environment leverages broadcast write functionality, allowing simultaneous data transmission for reflective semaphores and synchronization. Engineering teams deploying high-performance parallel processing structures in radar, sonar, or telecom base stations appreciate the seamless point-to-point and array configurations available through the processor’s link ports, with uncompromised throughput at 240 MBps over both link and external buses.
