Introduction

The TMS320R2812PGFS belongs to the family of digital signal processors or DSPs which enable sophisticated signal processing functions. This device has been developed by Texas Instruments and caters to specific requirements of embedded systems and system-on-a-chip designs. These types of processors provide solutions for basic functions and are designed around Harvard architecture which makes them great for implementations in embedded designs.

Application Field

The TMS320R2812PGFS can be used for applications such as interactive graphical user interfaces for consumer electronics, low to mid-level embedded control systems and wireless networking. In addition, the processor is often used in systems where high-end media and audio processing capabilities are needed.The processor is well-suited for appliance applications where a high level of features needs to be integrated on the system. The processor comes with an on-chip memory and has the necessary interfaces such as CAN, UART, and I2C needed to be connected to external communication networks or devices.The processor is also well-suited for voice and audio solutions thanks to its rich set of digital signal processor (DSP) instructions. It supports various sampling rates (8 kHz to 48 kHz) and can reach up to 65 MIPS maximum operations/second.

Working Principle

The TMS320R2812PGFS is based on an embedded processing core that is designed to act as a coprocessor to a host processor. The processor combines a mix of RISC and DSP features, making it suitable for use in solutions where both general-purpose capabilities and specialized signal-processing tasks need to be performed.At the heart of the TMS320R2812PGFS is a dual-issue RISC core with a two-level branch prediction mechanism, optimized for low power operation. Alongside the RISC core is a 16-bit VLIW multiplier allowing up to 8 simultaneous 16x16 bit multiplications per cycle. This multiplier can also access up to four 16-bit words from either on-chip or off-chip memories in a single cycle, so it can also be used to speed up memory-intensive operations.The processor also offers up to 64KB of single-cycle RAM and up to 512KB of on-chip Flash memory for storing code and data. The processor is also designed for low-power operation and utilizes a power-saving technique called SmartReflex to conserve energy.

Conclusion

The TMS320R2812PGFS is a powerful digital signal processor that provides ample features for embedded designs. It is ideal for applications that require processing of graphical user interfaces, embedded control systems, and audio/voice systems. The processor is based on an embedded processing core that combines RISC and DSP capabilities and is engineered for low-power performance. It has an on-chip memory, multiple interfaces, and a 16-bit VLIW multiplier allowing up to 8 simultaneous 16x16 bit multiplications per cycle.
