1.1.2 Flashcards
What are the advantages of CISC?(4)
Requires little RAM to store code(1) Compiler does little work to convert code to machine code as the code is very short(1)As it has a large amount of instructions.(1) In assembly for CISC the statement only takes one mnemonic(1).
What Devices use RISC?(1)
RISC processors are used in modern smartphones and tablets.(1)
What Devices use CISC?(1)
CISC processors are used in desktop and laptop computers.(1)
What are the disadvantages of CISC?(3)
CISC processors have complex components(1) therefore it is more expensive to make(1).Also for CISC processors have a varied instruction time , as it takes one clock-cyle for each instruction (1).
What are the advantages of RISC?(3)
RISC Processors have simple parts(1) therefore are cheaper to manufacture(1). As RISC consist of simple commands they take the same time to execute, therefore it runs programs quickly (1).
What are the disadvantages of RiSC?(3)
RISC Processors require multiple instructions for complex tasks (1) . It require several instruction for complex tasks so More RAM space required. When translating to machine code compiler needs to do more work to connvert langauge due to it having multiple mnuemonics (1).
Define Multi-core processor?(2)
More than one processing unit in a processor (1). Which can independently process instructions at the same time (1).
What is the difference between Parallel and Multicore processing? (2)
Parallel processing is when the instructions are not broken up and processed in one go (1). While Multicore, proce4ss sis broken up into threads and each core runs a differernt thread.
Define Parallel processor?(1)
Parallel processing is a method of simultaneously breaking up and running program tasks on multiple microprocessors in order speed up performance time.(1)
What is a GPU? (3)
A GPU is an (specialist)electronic circuit (1), that consits of thounsdands of efficient cores(1). Designed to handle mutliple tasks simultaneously(1)
Give 4 uses for GPU?(4)
Generally used in Machine learning Oil Exploration Image Processing Finacial Transactions & Bitcoin (1 for each point )
What are the Advantages of a GPU?(3)
Very Quick at performing basic tasks[Calacualtions to find Prime Numbers].(1)Increases computer perforamnce(1). Allows better computer graphics and so better video and gaming experiences (1 mark for either experiences)
What are the Disadvantages of a GPU?(2)
Due to Bitcoin and all other powerful computer GPUs have become more expensive(1).It requires/consumes a lot of energy to Power GPUs(1).
What is a co-processor? (1)
An extra processor used to supplement the functions of the primary processor
