The 80460 is a microprocessor unit (MPU) implemented by Intel in the late 1980s. This microprocessor is based on the Intel 80386 and Intel 80486 CPUs, and runs at 16 MHz, which provides superior performance in comparison to the earlier processors. It was developed to provide a high-performance processor for embedded applications, such as point-of-sale terminals, automotive systems, robotics, and aerospace applications.

The 80460 is a 64-bit microprocessor with a 32-bit data bus. It can address up to 4 Gigabytes of physical memory, and can be interfaced with several memory technologies, including DRAM, SRAM, and ROM. It has a 32-bit on-chip cache, providing up to 32K bytes of primary memory and 32K bytes of secondary memory. The 80460 contains an 8-level deep execution pipeline, which allows instructions to be fetched, executed, and stored in parallel.

The 80460 is designed to efficiently execute multiple programming languages, including assembly language, C, C++, Fortran, Java, and Visual Basic. It has a single-instruction multiple-data (SIMD) facility, which allows multiple instructions to be executed in parallel, thus increasing the speed and performance of applications. The 80460 also supports memory protection, which prevents applications from accessing memory outside of their allocated memory space. It also provides interrupt handling, allowing applications to take full advantage of its features.

This microprocessor has several applications in different fields. It is used in industrial automation, such as factory automation, robotics, and machine control. It is also used in embedded systems, such as point-of-sale terminals, automotive systems, and aerospace applications. It is widely used in consumer electronics, including game consoles, DVD players, and digital cameras. The 80460 is also used in medical and military systems.

The 80460 utilizes a superscalar architecture, which allows instructions to be executed in parallel. This architecture increases the throughput of the processor by fetching and executing instructions in parallel. In addition, the 80460 has several memory protection features, including segmentation, protection rings, and safe memory access. These features help to prevent unauthorized access to system resources and memory.

The 80460 is a highly versatile and powerful microprocessor. It has a wide range of application fields and is capable of tackling a variety of tasks. Its ability to use several programming languages, its high-speed performance, and its efficient memory protection features make it an excellent choice for embedded and industrial applications.
