# mips64 MIPS64 is a 64-bit Instruction Set Architecture (ISA) for computer processors. It was developed by MIPS Technologies, Inc., a company that designs and manufactures microprocessors and other semiconductor devices. The MIPS64 ISA is an extension of the [MIPS32](/pwn/architectures/mips32.md) ISA, which is a 32-bit ISA that was developed earlier by MIPS Technologies. It adds support for 64-bit integers, pointers, and addresses, as well as a number of other features designed to improve performance and versatility. Like the MIPS32 ISA, the MIPS64 ISA is a Reduced Instruction Set Computing (RISC) architecture, which means that it has a relatively small set of simple and easy-to-execute instructions. The MIPS64 ISA includes a wide range of instructions for performing arithmetic and logical operations, branching, and memory access, as well as support for floating point operations and multimedia instructions. It is used in a variety of systems, including embedded systems, networking devices, and desktop and server computers. Overall, the MIPS64 ISA is a powerful and flexible architecture that is known for its performance and efficiency. It has played a significant role in the development of many modern computing systems and continues to be a popular choice for a variety of applications. {% content-ref url="/pages/xQT7LrpqmZffftxBJj5Q" %} [Calling convention](/pwn/architectures/mips64/calling-convention.md) {% endcontent-ref %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
