DMIPS is Dhrystone MIPS. To help understand the meaning of this name, let’s divide it in two words and start with short explanation what is MIPS (million instructions per second), then try to get more familiar with the meaning of Dhrystone. Use the `unsigned long' rather than `__u32' type for DSP accumulator registers, like with the regular MIPS multiply/divide accumulator and general-purpose registers, as all are 64-bit in 64-bit implementations and using a 32-bit data type leads to contents truncation on context saving.

The MSR MAV 4 MIPS Helmet is a mid priced helmet with the MIPS technology typically only found in higher priced options. MIPS changes the way we think about helmet safety and was developed by brain surgeons and scientists to reduce rotational forces on the brain caused by angled impacts to the head.

the data segment is divided into 2 parts: static data and dynamic data do not confuse static data with the "static" keyword in Java and C in this context, static data are the memory locations whose addresses are known at the time the program is loaded into memory; in C this will be the global variables
