What is a false dependency?
What is a false dependency?
a read from a register or memory location must return the last prior value written to that location, and not one written programmatically after the read. This is a sort of false dependency that can be resolved by renaming. WAR dependencies are also known as anti-dependencies.
What are the symptoms of toxins in your body?
Symptoms of toxicity can be varied and may include: poor circulation, swelling, headaches, migraines, stress, anxiety, depression, allergies, poor skin, yeast, arthritis, fatigue, constipation, obesity, cellulite, sinus issues, gout, digestive disorders, cold/respiratory disorders, insomnia, bloating, and gas.
What is branch penalty?
The branch penalty is analyzed as a function of the relative number of branch instructions executed and the probability that a branch is taken. The resulting model shows the fraction of maximum performance achievable under the given conditions.
How do toxins affect the environment?
Toxic waste can harm people, animals, and plants, whether it ends up in the ground, in streams, or even in the air. Some toxins, such as mercury and lead, persist in the environment for many years and accumulate over time. Humans or wildlife often absorb these toxic substances when they eat fish or other prey.
What is name dependency?
• Name dependence: when 2 instructions use same register or. memory location, called a name, but no flow of data between the. instructions associated with that name; 2 versions of name.
What are toxic hazards?
Toxic materials are substances that may cause harm to an individual if it enters the body. Toxic materials may enter the body in different ways. Some materials can easily pass through unprotected skin and enter the body. Ingestion is another, less common, route of exposure in the workplace.
What are the five steps in MIPS instruction execution?
In general, let the instruction execution be divided into five stages as fetch, decode, execute, memory access and write back, denoted by Fi, Di, Ei, Mi and Wi. Execution of a program consists of a sequence of these steps. When the first instruction’s decode happens, the second instruction’s fetch is done.
What are the four steps in managing risks to health and safety?
The four steps for managing WHS risks are:
- Step 1 – Identify hazards. Find out what could cause harm.
- Step 2 – Assess risks.
- Step 3 – Control risks.
- Step 4 – Review control measures.
What are the 5 pipeline stages?
Following are the 5 stages of RISC pipeline with their respective operations:
- Stage 1 (Instruction Fetch)
- Stage 2 (Instruction Decode)
- Stage 3 (Instruction Execute)
- Stage 4 (Memory Access)
- Stage 5 (Write Back)
Is pipelining possible in CISC?
When pipelining is done with a CISC processor it is done at a different level. The execution of instructions is broken down into smaller parts which can then be pipelined. In effect, The CISC instructions are translated into a sequence of internal RISC instructions, which are then pipelined.
What are the 7 hazardous substances?
Orange or red. Square or diamond. They are hazard symbols given to chemicals and substances that are hazardous to health….Flammable
- Extremely flammable gas.
- Flammable gas.
- Extremely flammable aerosol.
- Flammable aerosol.
- Highly flammable liquid and vapour.
- Flammable liquid and vapour.
- Flammable solid .
How can you reduce risk in the workplace?
Some practical steps you could take include:
- trying a less risky option.
- preventing access to the hazards.
- organising your work to reduce exposure to the hazard.
- issuing protective equipment.
- providing welfare facilities such as first-aid and washing facilities.
- involving and consulting with workers.
Why is branch prediction algorithm needed?
The purpose of the branch predictor is to improve the flow in the instruction pipeline. Branch predictors play a critical role in achieving high effective performance in many modern pipelined microprocessor architectures such as x86.
How can we reduce hazards and risks?
What are Control Measures?
- Eliminate the hazard.
- Substitute the hazard with a lesser risk.
- Isolate the hazard.
- Use engineering controls.
- Use administrative controls.
- Use personal protective equipment.
What is control hazard?
Control hazards (branch hazards or instruction hazards) Control hazard occurs when the pipeline makes wrong decisions on branch prediction and therefore brings instructions into the pipeline that must subsequently be discarded. The term branch hazard also refers to a control hazard.
What should you do if you identify a hazard?
In order to control workplace hazards and eliminate or reduce the risk, you should take the following steps:
- identify the hazard by carrying out a workplace risk assessment;
- determine how employees might be at risk;
- evaluate the risks;
- record and review hazards at least annually, or earlier if something changes.
What are the 7 types of hazard?
The six main categories of hazards are:
- Biological. Biological hazards include viruses, bacteria, insects, animals, etc., that can cause adverse health impacts.
- Chemical. Chemical hazards are hazardous substances that can cause harm.
What are the 5 major types of hazards?
OSHA’s 5 Workplace Hazards
- Safety. Safety hazards encompass any type of substance, condition or object that can injure workers.
- Chemical. Workers can be exposed to chemicals in liquids, gases, vapors, fumes and particulate materials.
What are the most common hazards in a workplace?
- Common types of safety hazards in the workplace are: • Slips, trips and falls.
- Slips, Trips and Falls. • Bad housekeeping and poor drainage can make floors and other walking surfaces wet.
- Fire and Explosions.
- Transportation and Vehicle-Related Accidents.
- Confined Spaces.
How do you identify a hazard?
To be sure that all hazards are found:
- Look at all aspects of the work and include non-routine activities such as maintenance, repair, or cleaning.
- Look at the physical work environment, equipment, materials, products, etc.
- Include how the tasks are done.
- Look at injury and incident records.
What methods are used by RISC pipelining for data and control hazards?
A pipelined RISC architecture can be bifurcated in to five different stages, namely Instruction fetch, Instruction Decode, Execution, Memory and Write back. All of these stages work in a synchronous manner with each other and forward instructions to the next consecutive stage with each passing cycle.
What is debit branch penalty?
The penalty charged on delayed payment of instalment shall be. i) Penalty in case of delay in payment of installment of RD of 5 years or less shall be Rs 1.50 for every Rs 100 per month. ii) Such penalty shall be Rs 2.00 for every Rs. 100 per month for the account on more than 5 years.
What are the 2 types of hazards?
There are many types of hazards – chemical, ergonomic, physical, and psychosocial, to name a few – which can cause harm or adverse effects in the workplace..
What are the three types of hazard controls?
- Elimination and Substitution. The most preferred method of controlling risk is to eliminate the hazard altogether.
- Engineering Controls.
- Administrative Controls.
- Personal Protective Equipment (PPE)
What are bad toxins in your body?
It typically includes pollutants, synthetic chemicals, heavy metals, and processed foods — which all negatively affect health. However, popular detox diets rarely identify the specific toxins they aim to remove or the mechanism by which they supposedly eliminate them ( 1 ).
What is anti dependence in pipeline?
An anti-dependency, also known as write-after-read (WAR), occurs when an instruction requires a value that is later updated. The anti-dependency between 2 and 3 has been removed, meaning that these instructions may now be executed in parallel.
What are the hazards in pipelining?
There are three types of hazards: Structural hazards: Hardware cannot support certain combinations of instructions (two instructions in the pipeline require the same resource). Data hazards: Instruction depends on result of prior instruction still in the pipeline.
What is the best way to fix a hazard?
The best way to fix a hazard is to get rid of it altogether….3. Make the changes
- Elimination – Sometimes hazards – equipment, substances or work practices – can be avoided entirely.
- Substitution – Sometimes a less hazardous thing, substance or work practice can be used.
