Memory chip is the specific application of the concept of embedded system chip in the storage industry.Therefore, whetherSystem chipIt is also a memory chip that embeds software in a single chip to achieve multi-function and high performance, as well as support for multiple protocols, multiple hardware and different applications.
ASIC(ASIC）It has been widely used in the storage and network industries.In addition to greatly improving the system processing capacity and speeding up product research and development, ASIC is more suitable forMass productionAccording to the fixed demandStandardized design。In the storage industry, ASIC is usually used to realize some functions of storage product technology, and is used as an accelerator or to alleviate variousoptimization techniqueThe excessive load of CPU caused by the large number of operations of.
FPGA (Field Programmable Gate Array) isASIC(ASIC) is the highest level.Compared with ASIC, FPGA can further shortendesign cycle , lowerDesign cost, with higher design flexibility.When it is necessary to change the completed design, the redesign time of ASIC is usually calculated in months, while the redesign of FPGA is calculated in hours.This makes FPGA have a market unmatched by other technology platformsresponse speed。
The new generation FPGA has the characteristics of low power consumption, fast and fast (most tools are calculated in picoseconds - 10 billionths of a second).At the same time, the manufacturer canfunctional module andI/OThe module can be reconfigured or programmed online to realize online reconfiguration of the system.This allows FPGA to build a real-time customization based on computing taskssoft core processor 。In addition, FPGA functions are not limited, and can beStorage controller, or a processor.The new generation FPGA supports a variety of hardware, with programmable I/O, IP (intellectual property) andMultiprocessorBoth core and core.These comprehensive advantages make FPGA used by some storage manufacturers to develop full-featured products of memory chip architecture.
