When the scratchpad is a hidden portion of the main memory then it is sometimes referred to as bump storage. In some systems [ a ] it can be considered similar to the L1 cache in that it is the next closest memory to the ALU after the processor registers , with explicit instructions to move data to and from main memory , often using DMA -based ...
Scratchpad may refer to: . A pad of paper, such as a notebook, for preliminary notes, sketches, or writings; Scratchpad memory, also known as scratchpad, scratchpad RAM or local store, is a high-speed internal memory used for temporary storage of calculations, data, and other work in progress
Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.
A translation lookaside buffer (TLB) is a memory cache that stores the recent translations of virtual memory to physical memory. It is used to reduce the time taken to access a user memory location. [1] It can be called an address-translation cache. It is a part of the chip's memory-management unit (MMU).
In operating systems, memory management is the function responsible for managing the computer's primary memory. [1]: 105–208 The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding which gets memory, when they receive ...
There is no data cache in the architecture, but half of each SRAM bank can be used as a scratchpad memory. [62] Although this type of architecture allows unstructured parallelism in a dynamically non-contiguous memory system, it also produces challenges in the efficient mapping of parallel algorithms to a many-core system. [61]
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
In computer engineering, a load–store unit (LSU) is a specialized execution unit responsible for executing all load and store instructions, generating virtual addresses of load and store operations [1] [2] [3] and loading data from memory or storing it back to memory from registers.
