brk and sbrk are basic memory management system calls used in Unix and Unix-like operating systems to control the amount of memory allocated to the heap segment of the process. [1] These functions are typically called from a higher-level memory management library function such as malloc .
[11] [failed verification] When MIPS II was introduced, MIPS was renamed MIPS I to distinguish it from the new version. [3]: 32 MIPS Computer Systems' R6000 microprocessor (1989) was the first MIPS II implementation. [3]: 8 Designed for servers, the R6000 was fabricated and sold by Bipolar Integrated Technology, but was a commercial failure.
In the early 1990s, MIPS began to license their designs to third-party vendors. This proved fairly successful due to the simplicity of the core, which allowed it to have many uses that would have formerly used much less able complex instruction set computer (CISC) designs of similar gate count and price; the two are strongly related: the price of a CPU is generally related to the number of ...
The term is commonly used in association with a metric prefix (k, M, G, T, P, or E) to form kilo instructions per second (kIPS), mega instructions per second (MIPS), giga instructions per second (GIPS) and so on.

The CPU IP cores comprising the MIPS Series5 ‘Warrior’ family are based on MIPS32 release 5 and MIPS64 release 6, and will come in three classes of performance and features: 'Warrior M-class': entry-level MIPS cores for embedded and microcontroller applications, a progression from the popular microAptiv family
Code for a simple model implementation of a storage manager for Unix was given with alloc and free as the user interface functions, and using the sbrk system call to request memory from the operating system. [6] The 6th Edition Unix documentation gives alloc and free as the low-level memory allocation functions. [7]
Originally written in C++ for MIPS, Nachos runs as a user-process on a host operating system. A MIPS simulator executes the code for any user programs running on top of the Nachos operating system. Ports of the Nachos code exist for a variety of architectures. In addition to the Nachos code, a number of assignments are provided with the Nachos ...
