The correct answer is A. TEXAS TMS320.
The Harvard architecture is a computer architecture where instructions and data are stored in separate memories. This is in contrast to the von Neumann architecture, where instructions and data are stored in the same memory. The Harvard architecture was first used in the Harvard Mark I computer, which was built in 1944.
The TEXAS TMS320 is a family of digital signal processors (DSPs) that use the Harvard architecture. DSPs are specialized processors that are designed for processing digital signals, such as audio and video signals. The TMS320 family is one of the most popular families of DSPs, and it is used in a wide variety of applications, including mobile phones, digital cameras, and audio and video equipment.
The 80386, 80286, and 8086 are all microprocessors that use the von Neumann architecture. The von Neumann architecture is a more general-purpose architecture than the Harvard architecture, and it is used in a wider variety of applications. However, the Harvard architecture is better suited for applications that require high-speed processing of data, such as digital signal processing.
In conclusion, the correct answer to the question “Which of the following processors uses Harvard architecture?” is A. TEXAS TMS320.
