The processor uses temporary storage called to temporarily hold both data and instructions while it is processing them?
The processor uses temporary storage called primary storage, to temporarily hold both data and instructions while it is processing them. Another word for primary storage is called memory.
Why are RISC architectures referred to as Load-Store architectures?
RISC architectures generally have fewer instructions that operate directly on memory locations than CISC architectures. So, where a CISC machine will have instructions that operate directly on memory, in RISC this would be implemented as: Load from memory into register, do operation on register, store register back into memory. So a lot of the processing revolves around the Load-Store loop.
What are the advantages of RISC architecture over CISC?
CISC RISC Emphasis on hardware Emphasis on software Includes multi-clockcomplex instructions Single-clock,reduced instruction only Memory-to-memory:"LOAD" and "STORE"incorporated in instructions Register to register:"LOAD" and "STORE"are independent instructions Small code sizes,high cycles per second Low cycles per second,large code sizes Transistors used for storingcomplex instructions Spends more transistorson memory registers RISC-Means Reduced Instruction Set Computer.aRiscsystem has reduced number of instructions and moreimportantly it is load store architecture werepipelining can be implemented easily.Eg.ATMEL AVRCISC-Means Complex instruction set architecure.A CISCsystem has complex instructions such as directaddition between data in two memory locations.Eg.8085Simplicity of the instruction set means that they get processed faster (less branching). You get performance improvements if the gain in speed is not offset by the necessary increase in instructions.
What is the unit of random access memory?
Random access memory (usually known by its acronym, RAM) is a type of computer data storage. It takes the form of integrated circuits that allow the stored data to be accessed in any order - that is, at random and without the physical movement of the storage medium or a physical reading head. RAM is a volatile memory as the information or instructions stored in it will be lost if the power is switched off.source: Wikipedia
What is the cache memory used for?
Cache is a high speed buffer memory for storing automatically small areas of frequently used memory, so that the machine does not have to wait for the full memory access time every time it needs to access the data in those areas.Most computers have separate but similar cache memories for data and instructions. This allows the same access time advantages for both, but as data and instructions are usually in different places in memory eliminates any conflicts in usage.Some computers have multiple levels of different speed cache with different sizes. These are typically referred to as L1 cache, L2 cache, L3 cache, etc. with L1 being the fastest, most expensive, smallest size cache closest to the processor; the others are successively closer to the main memory.
A holding area that stores the data and instructions most recently called by the processor from RAM is called?
Cache memory
What are processor features?
Features of contemporary processors include a dual core and cache memory. They also have transistors for communicating information and instructions at the same time.
What is the term for very fast memory used to store data or instructions between the CPU and regular memory?
Very fast memory used to store data or instructions between the CPU and regular memory is called cache.
What is the memory of Pentium 1?
Pentium 1s are processors. They don't have memory.
What core processor has extended memory?
All of the processors shown have extended memory.
What is the data found in the cache is called?
The data found in the cache is called cache data. It typically consists of recently accessed or frequently used instructions or data that are stored in a smaller and faster memory area for quicker access by the processor.
What is a cache outside the processor called?
L2 cache. Today's processors all have some memory on the processor chip (called a die). Memory on the processor die is called Level 1 cache (L1 cache). Memory in the processor package, but not on the processor die, is called Level 2 cache (L2 cache). Some processors use a third cache farther from the processor core, but still in the processor package, which is called Level 3 cache (L3 cache).
The concept that a series of instructions for a computing task can be loaded into memory is called a stored?
program
The computer that can move data and instructions between storage and memory in a process is called?
sawpping
What do you call electronic components that store instructions waiting to be executed?
It's called CPU cache of level one.
How is the power of processors measured?
The power of processors (computers) are generally measured in MIPS, or Million Instructions Per Second. However, this is a subjective term because it depends on the instruction mix, cache hit/miss ratio, processor versus cache versus memory speed, and various other factors. Benchmark tests for processors are very complex, diverse, and relatively standardized so that useful comparisons can be made from them.
What is the meaning of near and far definition in microprocessor programming using C?
Fundamentally any pointer in C is a reference to a memory location somewhere in system memory. While this seems simple in theory, in practice this is more complex when the microprocessor architecture is considered. Two considerations in computer programs are code size and speed. For this reason microprocessors have some additional modes which help reduce code and speed up code execution. Microprocessors fetch instructions from memory and then act on them. Included in these instructions are the addresses of the memory on which they will act. Modern microprocessors can access 2^32 memory locations (or more.) Thus a full memory location would take 32 bits to encode. The instruction may get quite large and take some moderate time to load from memory. To improve this situation the microprocessor manufacturers create instructions with "short" memory locations where part of the address is stored internally in a register in the microprocessor and the rest is held in this shortened address. These registers are called segment registers (in Intel processors) and the memory references are called relative addressing modes. This background finally brings us to the meaning of near and far. A near pointer reference is quick for the processor to handle but can only reference 64k bytes of memory. A far reference contains the entire memory location specified and can therefore specify memory anywhere in the microprocessor, it is however quite a bit slower to execute. This is less of an issue in modern processors but the choice becomes near and fast but only access 64k or far and slower but the entire memory map.
