In this article, we discuss the impact of real-time requirements on embedded file system performances and RAM usage. We show how to calculate the amount of buffering needed to absorb a hypothetical sequence of write accesses of varying duration. We show how RAM usage, write access time and average throughput are interdependent under our real-time assumption.
In this particular article, we show how the maximum average write throughput on a given flash device varies with the amount of stored data. We provide a simple performance model that can be used for setting realistic performance expectations, comparing file system performances, and questioning application requirements with minimal assumptions regarding the actual workload or file system implementation.
In this article, we cover five aspects of embedded file systems that you should have in mind when deciding which one to choose, five essentials that you can’t ignore. This is by no means a complete guide to embedded file systems but it covers enough to avoid common mistakes, particularly among application engineers who have little prior experience with embedded file systems.
For this article, we look at Everspin’s EM064LX in the context of data storage applications, focusing on access speed metrics, that is average throughput and worst-case access latency. For context, we compare MRAM performances with NOR and NAND flash using a simple benchmark and discuss the implications of the obtained results from an application design standpoint.
In this article, we take a closer look at this promising new offering, focusing on differentiating factors compared to existing flash-based devices and previous MRAM implementations. We present 4 use case scenarios to illustrate how we believe the EMxxLX xSPI family can compete with current flash-based solutions and how it really changes the game for us embedded designers.
This article is all about emerging non-volatile (NVM) technologies, a complex and ever-evolving topic that has stimulated numerous research fields over the years, and engaged substantial investments from the biggest players in the semiconductor industry. The topic is also quickly gaining momentum among embedded developers.
In this article, we present a detailed discussion of SD card performances along with benchmarks for consumer and industrial-grade cards. The results help quantify the large variations in performance between individual devices and their impact on real-world performance.
Over the course of this article, we’ll go through the variations of the protocol used by QSPI NOR Flash devices. We’ll start simple, with the basic SPI protocol then move through the variations to reach some of the more complicated QIO, QPI and DDR variations.
QSPI NAND is a memory technology specifically designed as a direct alternative to its popular cousin, QSPI NOR. But what exactly is QSPI NAND? How does it compare to QSPI NOR? How does it compare to parallel NAND? This is what this article is all about.
In this article we’ll leave the package attributes behind to focus on the internal features of QSPI devices, starting with the memory organization. This article will cover the overall capacity, multi-stack devices as well as the memory map organization units such as pages, blocks and sectors.
