Digital signal processers (DSP) are specialized microprocessors that are intended for performing digital signal processing (DSP) operations. Texas Instruments (TI) manufactures and markets a line of digital signal processors called the TMS320 C54V90PGE. It is a high-performance and highly integrated digital signal processor (DSP) device specifically designed for digital signal processing tasks. It is a 32-bit processor with a dedicated memory interface, multiply-accumulate unit, multiple DMA channels and programmable I/Os. It is designed for power efficiency and software scalability.

Product Overview

The TMS320C54V90PGE is a high-performance, highly integrated device specifically designed for digital signal processing tasks. This device combines a powerful microprocessor, a memory interface, and a multiply-accumulate unit with a dedicated DMA controller, programmable I/O, and various other blocks for a complete DSP solution. It is designed for power efficiency and software scalability.

The TMS320C54V90PGE offers 32-bit performance with 64-bit CPU registers, 128-bit memory interface, and a 64-bit multiply-accumulate unit. The TMS320C54V90PGE operates in a little-endian or big-endian data format, allowing the user to choose the optimal data format for their application. Additionally, it is capable of operating at a VDD of 1.8V-3.3V, which provides power efficiency. The device also has an array of peripherals such as UARTs, SPI, and I2S, allowing for easy connection to external systems. The software development kit for the TMS320C54V90PGE also includes powerful real-time debug, trace, and variable access features to aid in debugging and evaluation.

Application Field and Work Principle

The TMS320C54V90PGE is suitable for use in a range of embedded applications requiring maximum performance and software scalability. It is ideal for applications such as audio processing, video processing, motor control, and communications. The TMS320C54V90PGE excels in high-performance, real-time digital signal processing tasks due to its high-speed architecture, integrated memory controller, and low-power consumption.

The TMS320C54V90PGE is based on the Varius architecture, which is optimized for digital signal processing tasks. The Varius architecture uses a Variable-Length Instruction Set (VLIS) to dynamically and efficiently select a subset of instructions which best suit the program being run. This allows the system to optimize its execution, resulting in higher throughput and power savings. The TMS320C54V90PGE supports up to 256MBytes of external memory, giving it the scalability to handle data-rich applications.

The TMS320C54V90PGE also offers powerful DMA capabilities that allow for fast and efficient data transfer. The device has 10 DMA channels with 12-bit resolution, allowing for efficient data transfer with minimal software intervention. It also supports up to two direct memory access engines for high-speed data transfer.

The TMS320C54V90PGE also features a high-speed, integrated memory controller and separate data and address buses. The memory controller supports up to 64MBytes of on-chip memory, and can be configured as multiple levels of stacked memories. This allows the system to quickly access and process data without having to wait for data to be fetched from external memory. The TMS320C54V90PGE also comes with a range of peripherals such as UARTs, SPI and I2S for external I/O, and four programmable timer channels for sensing.

In summary, the TMS320C54V90PGE is a high-performance, highly integrated device specifically designed for digital signal processing tasks. Its high-speed architecture, integrated memory interface, and low-power consumption make it suitable for a wide range of embedded applications requiring maximum performance and scalability. The device is capable of supporting a range of peripherals and memory, and its separate data and address buses, and powerful DMA controllers provide excellent data throughput and reduced processor load.
