Making Sense of Flash File System Performances

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.

5 Things to Consider When Choosing an Embedded File System

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.

Everspin MRAM Performance Benchmark Comparison

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.

First Look at Everspin’s New xSPI STT-MRAM Lineup

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.

Zynq-7000 Bare-Metal Benchmarks

In this article we’ll look at some well-known CPU benchmarks, namely CoreMARK, Dhrystone, Whetstone and Linpack. Following that, we’ll look at the memory bandwidth and latency of the external DDR memory, On-Chip RAM and block RAM (BRAM) in the FPGA. Finally, we’ll round up with numbers on interrupt latency.

QSPI NOR Flash Part 3 — The Quad SPI Protocol

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.
