Embedded - DSP (Digital Signal Processors)

The ADSP-2184NBSTZ-320 is an embedded Digital Signal Processor (DSP), part of the famous ADSP-21K family of processors from Analog Devices. It is a 400MHz 16-/32-bit floating-point DSP that combines powerful performance, high speed peripherals and rich, on-chip memory all into a compact BGA package. This powerful DSP is suitable for a wide range of industrial, medical and commercial applications such as VoIP, radar systems, medical imaging, video processing, and so on.

Application Field

The ADSP-2184NBSTZ-320 is a multicore embedded processor. The processor includes 4 cores, including the main core and three coprocessors. It also provides high speed Memory Interfaces, as well as a wide range of peripherals such as Ethernet, USB, UART, CAN, SPI, Ethernet, I2C, and so on. This makes the ADSP-2184NBSTZ-320 suitable for applications such as radar systems, video processing, medical imaging, VoIP, and so on.

Working Principle

The ADSP-2184NBSTZ-320 uses a simplified RISC architecture which consists of four 32-bit flags, 23 sequentially mapped registers, and a single instruction databus. The processor core comprises four longword-level execution units. Each unit has its own instruction and data busses with three shifters, two multiplier registers and two accumulators. The four units are interconnected to enable multiple operations to occur simultaneously on different data streams.

The ADSP-2184NBSTZ-320 also includes on-chip memory. The main memory is a high-density three-channel RAM array with parity support that is organized as 128 Mbytes of DRAM. In addition, the memory also includes a 4Kbyte scratchpad memory and a 32Kbyte instruction cache. This on-chip memory allows for fast access times and more efficient memory utilization.

The processor also includes on-chip peripheral support, including Ethernet, USB, UART, CAN, SPI, Ethernet, I2C, and so on. This allows the ADSP-2184NBSTZ-320 to be used in a wide range of applications, such as medical imaging, video processing, VoIP, and so on.

In addition to the on-chip peripherals, the ADSP-2184NBSTZ-320 also supports external peripherals through the four high-speed external buses, which can run at a maximum speed of 400MHz. This allows the processor to be connected to a wide range of external devices, such as peripheral cards, ASICs, FPGAs, and so on.

The ADSP-2184NBSTZ-320 also has two on-chip debug (JTAG) ports, which allow the programmer to debug or trace code during development. This makes it easier for the developer to locate and fix any bugs or problems in their code.

The ADSP-2184NBSTZ-320 is also a highly power efficient DSP, consuming only 5W at full speed load. This makes it an ideal choice for applications where low power consumption is essential, such as medical and industrial applications.

In conclusion, the ADSP-2184NBSTZ-320 is a powerful and highly integrated embedded processor that is suitable for a wide range of industrial, medical, and commercial applications. It combines on-chip memory and a wide range of peripherals to provide a powerful solution for embedded processor applications.
