TMS320DM643AZDK6 is a digital signal processor (DSP). It is a 32-bit, fixed-point device that can be used for embedded applications, such as image processing, audio/video encoding and decoding, radar/sonar filtering, and other DSP-related tasks.
This DSP is based on Texa’s TMS320C64x+™ DSP core. It includes 64KB of instruction and data memory, up to 24K of on-chip program RAM, and 32K of on-chip data RAM. The device also features an advanced 16-bit streaming data bus interface, an improved Digital Signal Processor-bus interface, and an enhanced JTAG/OnCE (Joint Test Assembly and Debug/On-Chip Emulation) module.
The TMS320DM643AZDK6 is designed to provide a complete development platform for embedded applications. It offers an advanced real-time operating system, optimized development tools and a range of task-specific embedded libraries. The device also features an advanced debug module, which supports both JTAG and OnCE interfaces.
The application field of the TMS320DM643AZDK6 includes automotive and consumer electronics, communications and industrial, medical and military. It can be used for projects that require sophisticated DSP algorithms and require real-time operation.
The working principle of the TMS320DM643AZDK6 is based on the architecture of the TMS320C64x+™ DSP core. This core is an optimized version of the TMS320C64x DSP core, which is based on a superscalar, five-stage RISC architecture. This core architecture provides fast computation times, a small footprint, and low power consumption.
The core consists of 32 32-bit general-purpose registers, 32 32-bit arithmetic/logic registers, a 64-bit accumulator, and a 16-bit multiplicand register. The device also has a 32-bit memory address bus and a 32-bit address generation unit (AGU). This AGU is used in conjunction with the various addressing modes to generate effective addresses.
In order to execute instructions, the TMS320DM643AZDK6 core executes eight instructions in parallel, using an instruction issue and dispatch unit. This unit arbitrates between five functional units—the two 16-bit ALUs (arithmetic logic units), the 16-bit multiplier/divider, the 64-bit accumulator, and the 32-bit memory access unit. The ALU operations generally involve 32-bit data, while all other operations are 16, 32, or 64-bit operations.
The TMS320DM643AZDK6 device can also be programmed to use multiple program or data memories, or use a single memory. For example, the user can decide to use a single 64KB program memory, one 32KB data memory and one 32KB program memory, or two 32KB program and data memories for a total of 128KB of memory. This makes the device very versatile and allows for different applications.
The TMS320DM643AZDK6 is a very powerful and versatile DSP, suitable for a multitude of embedded applications. It offers excellent development tools, an advanced debug module, and an optimized real-time operating system. It can easily accommodate multiple program and data memories and is ideal for tasks that require sophisticated DSP algorithms and real-time operation.
