Which register is used to store the result of any operation?
accumulator register
Which logic operations are performed in registers?
➢ Arithmetic Micro-operations: Perform arithmetic operation on numeric data stored in registers. ➢ Logical Micro-operations: Perform bit manipulation operations on data stored in registers. ➢ Shift Micro-operations: Perform shift operations on data stored in registers.
Is it better to have a few or many general purpose registers?
The benefit of having a large number of registers depends on the workload and the latency and parallelism of the hardware. Fujitsu’s SPARC64 VIIIfx provided more registers than Itanium, but specifically targeted high performance computing.
Is Ram better than cache?
“The difference between RAM and cache is its performance, cost, and proximity to the CPU. Cache is faster, more costly, and closest to the CPU. Due to the cost there is much less cache than RAM. For best performance the faster more expensive storage is closer to the CPU.
Is Ram more important than cache?
The cache needs to be much faster than main memory….Difference between RAM and Cache :
| S.No. | RAM | CACHE |
|---|---|---|
| 4. | It holds programs and data that are currently executed by the CPU. | It holds frequently used data by the CPU. |
| 5. | It is not fastest as compared to cache. | It is faster. |
Is 8MB Cache good?
So, 8MB doesn’t speed up all your data access all the time, but it creates (4 times) larger data “bursts” at high transfer rates. Benchmarking finds that these drives perform faster – regardless of identical specs.” “8mb cache is a slight improvement in a few very special cases.
Is 8mb cache better than 6mb?
Larger caches can store more data and can lead to faster performance in some applications. Larger cache size however does not necessarily mean faster performance in all tasks. Many applications do not require a lot of space in the cache to run optimally.
Is a 16 MB cache good?
I would personally go for a 32MB Cache drive, there’s quite a few around and at a great value. The difference between 8MB and 16MB isn’t so much but it might be noticeable in some things that you do. There’s no one thing that will make you fast, it’s a little tuning here, a little tuning there….
What is a Cacheline?
A cache line is the unit of data transfer between the cache and main memory . Typically the cache line is 64 bytes. The processor will read or write an entire cache line when any location in the 64 byte region is read or written.
Which cache level is fastest?
L1 (Level 1) cache is the fastest memory that is present in a computer system. In terms of priority of access, the L1 cache has the data the CPU is most likely to need while completing a certain task. The size of the L1 cache depends on the CPU.
