The need for quicker, more compact, and more effective gadgets is growing as technology develops. Modern VLSI (Very Large Scale Integration) designs, which are employed in the production of integrated circuits, have been created in response to this requirement (ICs). These modern VLSI designs are intricate, though, and in order to fully realise their potential, memory and storage must be carefully optimised. We shall examine some advice for current VLSI architectures’ memory and storage optimisation in this post.
Use low-power memory
Controlling power consumption is one of the main difficulties in contemporary VLSI design. Use of low power memory technologies like SRAM (Static Random Access Memory) and DRAM is crucial for memory and storage optimisation (Dynamic Random Access Memory). These technologies are more suitable for usage in contemporary VLSI designs since they demand less power than conventional memory technologies.
Use compression strategies
Using compression techniques is another option to improve memory and storage in contemporary VLSI systems. By lowering the amount of memory needed to store data, compression can improve performance while lowering power usage. Huffman coding, arithmetic coding, and Lempel-Ziv-Welch (LZW) coding are a few common compression methods.
Employ Cache Memory
The performance of contemporary VLSI design automation can be enhanced by the use of cache memory. In order to speed up access to frequently accessed data, it operates by storing it close to the processor. It is possible to decrease the time it takes the processor to access data by employing cache memory, which can lead to considerable performance gains.
Boost Data Structures
Performance can be greatly impacted by how data is structured in memory. In contemporary VLSI designs, it is crucial to adopt data structures that are optimal for the particular application in order to reduce memory and storage requirements. For instance, using a hash table data structure, which might offer quick search times, may be advantageous if the application involves a lot of searching.
Make use of multilevel memory hierarchies
Multi-level memory hierarchies, which are made up of different levels of memory with variable speeds and sizes, are frequently used in modern VLSI systems. Performance can be increased by adopting a multi-level memory hierarchy to store often accessed data in faster, smaller memory while less frequently accessed data is kept in slower, larger memory. This may shorten the time it takes to access data, which may lead to noticeable performance gains.
Use memory-management strategies
Modern VLSI architectures can benefit from the usage of memory management techniques like virtual memory and paging to optimise memory and storage. By temporarily moving data from RAM to disc, virtual memory is a technique that enables a computer to use more memory than it actually has. A related method is called “paging,” which divides memory into pages that can be loaded into RAM as needed. It is possible to optimise memory usage and lower the amount of memory needed to hold data by employing memory management strategies.
Use data compression for archiving
It is also feasible to apply data compression for storage in addition to memory compression approaches. As a result, the quantity of storage needed to hold data may be reduced, which may save storage costs and boost performance. Gzip, bzip2, and LZMA are a few well-liked methods of data compression for storage.
Put parallel processing to use
A task is divided into smaller subtasks for simultaneous processing on several processors as part of parallel processing. By lowering the amount of time needed to finish a task, parallel processing can increase performance. It is crucial to design the system to take use of parallel processing in order to optimise memory and storage in contemporary VLSI architectures. To maximise the advantages of parallel processing, it could be required, for instance, to optimise memory access patterns and make sure that data is separated into reasonable-sized pieces.
Use pipelines
Pipelining is a method that divides a task into smaller components that can be executed concurrently. By lowering the amount of time it takes to execute a task, pipelining can increase performance. Modern VLSI designs should be constructed to take full advantage of pipelining for memory and storage optimisation. To maximise the advantages of pipelining, it could be required, for instance, to optimise memory access patterns and make sure that data is separated into reasonable-sized pieces.
Use cutting-edge memory techniques
Advanced memory technologies like HBM (High Bandwidth Memory) and 3D NAND Flash memory can be used in modern VLSI designs. Modern VLSI designs can benefit from using HBM because of its high bandwidth and low power consumption. In contrast to conventional NAND Flash memory, 3D NAND Flash memory uses a stacked memory cell structure to offer increased density and reduced power consumption.
Minimize Memory Accesses
Accessing memory is a relatively slow process compared to other operations, so minimizing the number of memory accesses can significantly improve performance. One way to reduce memory accesses is to use data locality techniques that keep frequently accessed data together in memory, reducing the need to access multiple memory locations. Another way is to use prefetching techniques that bring data into cache before it is needed, reducing the need to wait for data to be loaded from memory.
Use Memory Controllers
Memory controllers are specialized chips that manage the communication between the processor and memory. Using a memory controller can improve performance by optimizing memory access patterns and reducing memory access latency. It can also provide additional features such as error correction and power management.
Use Non-Volatile Memory
Non-volatile memory, such as flash memory, retains data even when the power is turned off. This makes it useful for storing data that needs to be retained even when the device is turned off. Non-volatile memory can be used for storage and for cache memory, reducing the need to reload data after the device is powered back on.
Modern VLSI memory and embedded technology solution is a challenging endeavour requiring careful consideration of many different aspects. The performance and efficiency needed for contemporary VLSI designs can be attained by using low power memory technologies and advanced memory technologies. The optimisation of memory and storage in VLSI designs will remain a significant challenge that calls for constant innovation and advancement as technology progresses.
