The Definitive Guide to ARM® Cortex®-M3 and Cortex®-M4 Processors

This is a very good book for low level programming.

A MUST have if you want to get your AAME exam passed!

Il mérite très largement les 5 étoiles, peut être même six si j'avais eu le choix. Une page web donne même les erreurs du livre et leurs corrections.Si vous voulez mieux comprendre les mcu atmel, stm32 et autres il vous faut ce livre.Il est technique et pas du tout pour les débutants, il faut tout de même avoir quelques connaissances préalables sur les mcu et sur la programmation en c.Un très bon achat.

This is a monumental work. It covers everything from a high-level overview of the company (ARM) and how they do business (a fab-less IP company) to the low-level instructions offered by each of their microcontroller families (M0-M4).I was wondering how different this update would be to the 2nd edition. It is not just a cursory update with references changed to include the M4 (although there is some of that). There is a large amount of new material, including the new floating point and DSP instructions available on the Cortex M4. Lot's of other new material has been included.There is a great introduction about why ARM, and specifically the Cortex matter. It is *very* well-done and includes a huge set of diagrams.There is a lot to like:* Typeset well, clearly laid out* Interesting background (ARM, processors, differences between families)* Cortex M4 coverage* Good overview diagrams (such as a single page diagram showing the M0, M0+, M1, M3, and M4 instruction differences).* Breadth (high-level overviews, all the way down to very low-level processor details)* Sample code (how to utilize certain instructions to build an OS, for example)The code examples are especially surprising and welcome. A lot of effort was put into showing how certain features would be used: the SysTick timer, shadowed stack pointer, MPU, FPU, DSP, Sleep (WFE/WFI), etc. Actual C code is given (and explained), showing how to utilize each of these features (and others). C is used where possible, but mixed assembly is used where it makes sense. For example, on page 342 of the Context Switching example.This is an impressive work. But is there any room for improvement? Of course there would be some small things, such as improving the grammar (such as when software code is repeatedly called "software codes"), reformatting some diagrams to fit better (p545-48, p551-58, 618, ...) are unnecessarily in landscape orientation, yet do not utilize the extra space), and some examples in the SIMD section. The M4 has a large number of SIMD and saturating instructions, most of them duplications because of operand size or such. It would be helpful to have an explanation of which ones to use when.The index is good for reference and is almost too detailed. One issue is that the entry for CMSIS-RTOS gives only a single page (p48), with no mention to p607 section 19.1.3 "Role of CMSIS-RTOS".Reviews of other editions have noted that there are a lot of references to Keil tools. Those references are still here in this update, but IAR is also mentioned in a couple of places. Although it does get old seeing "Keil" mentioned repeatedly, GCC is also covered at times. Very nice.The breadth of this book is impressive. From the excellent new DSP coverage, to debugging support and techniques, to the Advanced Topics and Software Porting chapters, there is such a wealth of useful information that this 3rd edition feels more like a new book than just an update.

Das Buch wurde zur Vorbereitung auf die Zertifizierung zum ARM Accredited Engineer beschafft. Da es als Lehrbuch zum Selbststudium geschrieben wurde und nicht als reine Dokumentation wie ein Datenblatt macht es seinen "Job" sehr gut. Ich habe bis jetzt noch kein Detail vermisst, hätte mir aber praktische Programmiertips für Umsteiger gewünscht, also Erläuterungen welche von anderen Prozessoren bekannte "Tricks" beim Cortex-M3/M4 eher hinderlich sind und auf welche gewohnte workarounds man dank ARM-Raffinessen wie bit-banding, saturated add etc. verzichten kann. Das ist schon der einzige "Mangel" den ich in diesem Buch finde, im Vergleich zu anderen Büchern gleichen Themas didaktisch sehr gutes Lehrbuch, sehr umfänglich und aktuelles Fachbuch und preislich ein wahres Schnäppchen.Anfänglich hab ich mir ein Buch gewünscht das auch Cortex-A (Smartphones, Xilinx Zynx, Raspberry2) abdeckt aber das wäre wohl Anbetracht der Fülle an Info zuviel gewesen.
