Flash 101: NAND Flash vs NOR Flash - Embedded
Jul 23, 2018 · The downside of smaller blocks, however, is an increase in die area and memory cost. Because of its lower cost per bit, NAND Flash can more cost-effectively support smaller erase blocks compared to NOR Flash. The typical block size available today ranges from 8KB to 32KB for NAND Flash and 64KB to 256KB for NOR Flash.
UART Protocols and Applications in Embedded Systems
Jan 20, 2021 · Here are the steps to follow: First: Check the data sheet interface of the device.. Figure 14. Microcontroller data sheet. Figure 15. Microcontroller memory map. Second: Under memory map, check the UART address.. Third: Check the specific details for the UART PORT such as the operation mode, data bits length, the parity bit, and stop bits.Sample UART port details in data sheet:
ARM Thumb Instruction Set - Embedded
Sep 24, 2003 · The Thumb instruction set consists of 16-bit instructions that act as a compact shorthand for a subset of the 32-bit instructions of the standard ARM. Every Thumb instruction could instead be executed via the equivalent 32-bit ARM instruction. However, not all ARM instructions are available in the Thumb subset; for example, there’s no way to ...
Ring Buffer Basics - Embedded
Aug 7, 2013 · The ring buffer usually has two indices to the elements within the buffer. The distance between the indices can range from zero (0) to the total number of elements within the buffer. The use of the dual indices means the queue length can shrink to zero, (empty), to the total number of elements, (full).
Direct Memory Access (DMA) - Embedded
Oct 14, 2003 · Direct memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory without having each byte (or word) handled by the processor. Thus DMA enables more efficient use of interrupts, increases data throughput, and ...
Embedded Software Testing Basics
Feb 7, 2011 · Embedded Software Testing Basics. Test is the last step in traditional software development. We gather requirements, do high level design, detailed design, create code, do some unit testing, then integrate and start—finally— final test .
Flash 101: The NAND Flash electrical interface - Embedded
Aug 22, 2018 · The maximum throughput achievable was improved to 133 MBps in ONFI 2.0 and up to 200 MBps in ONFI 2.1. The electrical interface and throughput for ONFI 2.2 and 2.3 remain the same; these updates were aimed at optimizing the commands for improving the efficiency of larger systems and to support the ECC ZERO NAND (EZ-NAND) interface.
Firmware Architecture In 5 Easy Steps - Embedded
Sep 21, 2009 · Step 5: Plan for change. The third key consideration during the firmware architecture phase of the project is the management of feature diversity and product customizations. Many companies use a single source code base to build firmware for a family of related products.
eDP: A Better Embedded Display Ecosystem
May 2, 2016 · Designed to replace the internal LVDS display interface developed in the mid 1990s, eDP is used in virtually all new computers with an internal display, including laptops, all-in-ones, and many high-end, higher-resolution tablets. The development of both DisplayPort and eDP was driven by a variety of computing needs.
