Not entirely sure which route to take here. For context, I'm trying to divide by 2 to get the number down to just 1, but this isn't possible if the nubmer is negative so I want to make it positive first in order to achieve this.

I'd like to give some additional information because Jester already gave the correct answer :. Two's complement This is the most common way integer numbers are stored because on most CPUs including MIPS integer operations like addition, subtraction will automatically give the correct result when using two's complement.

You are calculating checksums for the internet one's complement : In this case you have to invert all bits. You could instead x xor -1 or -1 -x. But xori uses an unsigned You are processing floating point numbers by using integer instructions and want to invert the sign: In this case you have to change the sign bit. This is done using x xor 0x You would do this if you have a CPU without floating-point support and you have to emulate floating-point operations using integer operations.

If you have a CPU with floating-point support, you would normally not do this. However, you could also do this if you first copy the floating-point register to an integer register using mfc1 and after the operation you copy the value back using mtc1.

The MIPS concept can be used to measure eco-efficiency of a product or service and applied in all scales from a single product to complex systems. The calculation takes into account materials required to produce a product or service. The total material input MI is divided by the number of service units S.

For example, in case of a passenger car, the number of service units is the total number of passenger kilometres during the whole life span of the vehicle. The lower the material input per kilometre, the more eco-efficient is the vehicle. The whole life-cycle of a product or service is measured when MIPS values are calculated.

When a single product is examined, the MIPS calculations reveal the magnitude of resource use along the life-cycle and help to focus efforts on the most significant phases to reduce environmental burden of the product. There are two ways to reduce the material consumption per unit of service, the material input MI of the product can be reduced or amount of service units S can be increased. Material input in the production phase can be reduced by using less energy or raw materials. Also transport chains can be rationalized.

In the use phase the material input per unit of service can be reduced when amount of service produced is increased. For instance in case of a newspaper the material input can be reduced by using recycled paper instead of primary. Material input per reader decreases when the same paper is shared with several persons.

High quality products and availability of spares potentially increase the service life of the product. When the service life of a product is increased, the material consumption per unit of time decreases. Usually services like car sharing also help to reduce MIPS values since fewer products are needed to produce the service for greater number of people.

The Factor X concept was coined by Prof. Friedrich Schmidt-Bleek. The Factor Ten Club founded in and the Factor 10 Institute founded in support the dematerialization target.

Negative Numbers in Binary

It has been proposed that material flows in the industrialized countries should be decreased by factor 10 to reach more sustainable level of material use. Aim of factor targets is to increase resource productivity and increase the wealth created from the resources.

The factor concept can be applied on microeconomic and macroeconomic levels. For instance the Wuppertal Institute presents micro-level best practices related to Factor Four guideline.

The MIPS method can be used to measure natural resource consumption in five categories, viz. Biotic resources refer to renewable resources like plant biomass.This instruction adds the two operands together, and stores the result in the destination register.

Negative numbers are handled automatically using two's complement notationso different instructions do not need to be used for signed and unsigned numbers. The sub instruction subtracts the second source operand from the first source operand, and stores the result in the destination operand. In pseudo-code, the operation performs the following:.

Both add and sub trap if overflow occurs. However, some programming systems, like C, ignore integer overflow, so to improve performance "unsigned" versions of the instructions don't trap on overflow. The multiply and divide operations are slightly different from other operations. Even if they are R-type operations, they only take 2 operands. The result is stored in a special bit result register. We will talk about the result register after this section.

This operation multiplies the two operands together, and stores the result in rd. Multiplication operations must differentiate between signed and unsigned quantities, because the simplicity of Two's Complement Notation does not carry over to multiplication. The mult instruction multiplies and sign extends signed numbers. The result of multiplying 2 bit numbers is a bit result.

We will discuss the bit results below. The multu instruction multiplies the two operands together, and stores the result in rd. This instruction is for unsigned numbers only, and does not sign extend a negative result. This operation also creates a bit result. The div instruction divides the first argument by the second argument. The quotient is stored in the lowest bits of the result register. The remainder is stored in the highest bits of the result register.

Like multiplication, division requires a differentiation between signed and unsigned numbers. This operation uses signed numbers. Like the div instruction, this operation divides the first operand by the second operand.Did you know that multiple vehicles can use the same permit.

Neil Jones, market segment manager for application security: A major data breach or a physical security incident will result in casual users taking location tracking capabilities on their mobile applications much more seriously.

Applications will also be more likely to inform users that location information is being easily provided to other global users of the apps. Rohan Ramesh, senior product marketing manager for Watson for Cyber Security: We are moving toward a more connected world with the Internet of Things (IoT) and rapid evolution of technology and software.

With rapid innovation, businesses and individuals that are slow to upgrade or keep up with the latest software are left with unsupported software and systems that may have unpatched vulnerabilities.

### MIPS Assembly/Arithmetic Instructions

My prediction is that the majority of hackers will take advantage of these unpatched and unsupported systems, as they have been in recent years, to cause greater damage to reputation and financial bottom line. Therefore, endpoint hygiene is still going to be a high priority as computing power and business logic moves from the cloud to devices for real-time processing of information. James Murphy, offering manager for Watson IoT Platform: The value of the IoT to society and business will grow as the number and variety of devices connecting to the internet continues to expand.

Having access to a trusted IoT platform will be the first step in the right direction. Just like the adoption of the smartphone, the IoT will be ubiquitous and expected in everyday life. However, it will take trusted partnerships to sustain the integrity and security posture of those IoT solutions. Individuals and businesses will have to master the basics of IoT security. IoT security and operational integrity will be best addressed though shared responsibility and a multipronged approach to help realize the value of IoT solutions.
