The TMS320C28343ZFEQ is one of the newest generations of Digital Signal Processors (DSP) used in embedded systems. It is a 32-bit processor that is designed to address a variety of embedded applications requiring high-speed real-time processing power, including data acquisition, real-time signal exchange, communication, industrial automation, home and building automation, as well as automotive, medical and aerospace applications.

The TMS320C28343ZFEQ is a highly integrated DSP core with on-chip peripherals and 16KB of flash memory for non-volatile storage. It features a multi-channel Direct Memory Access (DMA) controller, on-chip universal analog and digital I/O, and a range of communication interfaces that support common protocols such as CAN, LIN, USB and Ethernet. The chip also comes with various advanced features such as an integrated USB stack and support for LDRA Tool Certification and Safety Certification. This makes it ideal for embedded systems needing high-speed real-time processing power and low-level peripherals.

The TMS320C28343ZFEQ operates at a maximum of 200 MHz using a programmable, 32-bit RISC operating environment. It includes 16K bytes of onboard flash memory and 32K bytes of onboard RAM for storage of data and instructions. It also has an on-chip, programmable analog-to-digital conversion capability, allowing time-critical signal processing tasks to be carried out on a continuous basis.

The TMS320C28343ZFEQ DSP uses an underlying Von Neumann architecture for its processor core. This architecture enables simultaneous execution of instructions and data, giving the processor a greater level of efficiency and improved performance. The RISC architecture allows for simpler instructions, with only 16 instructions that can be used by the processor. All instructions are 32 bits in length and can operate on 16-bit, 13-bit and 11-bit data.

The TMS320C28343ZFEQ architecture also supports a number of dedicated hardware features that reduce the amount of software engineering needed to implement embedded systems. These features include an optimized programmable algorithm accelerator (OPA) and an on-chip debug module that allows for real-time software development and debugging. The OPA is architected as a two-dimensional 8-way parallel array and integrated with the internal processor’s instruction caches, allowing for fast signal processing of critical functions.

The TMS320C28343ZFEQ also includes an on-chip memory management unit (MMU) that provides the ability to reprogram system memory at runtime. This enables the processor to share data between multiple threads and processes, which is especially useful in embedded systems where multitasking is required. The memory management unit can also be used to manage the use of dedicated hardware such as the programmable algorithm accelerator and the on-chip debugger module.

In terms of system design and development, the TMS320C28343ZFEQ is well suited to embedded applications requiring responsiveness, reliability and multi-threaded operation. The dedicated hardware features and RISC instruction set provide a significant advantage over some other embedded DSPs. Furthermore, the on-chip USB stack and support for LDRA Tool Certification and Safety Certification make it ideal for applications such as home and building automation.
