The NS486SXL-25 microprocessor is an embedded microprocessor manufactured by National Semiconductor and released in the early 1990s. The chip is quite powerful for its time, being based on a 32-bit MIPS processor architecture with an on-chip memory and cache. It also featured advanced power saving capabilities for the time, such as power gating, rate down scaling, and dynamic control of system bus speeds and power supply voltages.

The NS486SXL-25 is intended for use in embedded systems, providing the computing power necessary to run digital signal processing (DSP) algorithms, real-time applications, and other duties that must be completed in a short time. It is also used in many consumer electronics, particularly in the gaming industry, where it provides the computing power to run sophisticated 3D graphics.

The chip is designed around a three-phase bus scheduling architecture, which allows the processor to control multiple tasks and prioritize them based on the type of data being processed. This allows the processor to efficiently complete operations while providing the highest level of performance. In addition, the chip also supports direct memory access (DMA) transfers, allowing it to access memory quickly without having to go through the full processor cycle.

The NS486SXL-25’s architecture also allows it to support multiple peripherals on the same bus with minimal interference. This is done by using dedicated multiplexers, which are responsible for routing data from the processor to the appropriate peripheral. This means that the processor can control multiple peripherals without compromising performance or throughput, making it ideal for embedded systems.

The processor is also capable of running at a number of different clock rates, ranging from 12MHz to 25MHz. This allows it to scale in performance with the requirements of the application, while still ensuring a stable power consumption and good performance. This makes the NS486SXL-25 a great choice for embedded systems where the power consumption needs to be kept as low as possible.

Finally, the NS486SXL-25 is also able to support several external memories, including static RAM (SRAM), dynamic RAM (DRAM), and Flash memory. This allows applications to use multiple memory technologies, which can be used to store large amounts of data or code. This makes the processor well-suited for applications that need to store large amounts of data or code.

In summary, the NS486SXL-25 microprocessor is a powerful and versatile embedded processor, with a range of features that make it ideal for embedded systems. Its three-phase bus scheduling architecture, multiple clock rates, and support for multiple external memories makes it well-suited for embedded systems that require a high level of performance and low power consumption. Additionally, its support for multiple peripherals on the same bus provides the flexibility needed for applications that require multiple peripherals. All these features make the NS486SXL-25 ideal for embedded applications, giving it great potential for a wide range of applications.
