◆ A portion of code within a larger program. Often called
a subroutine or procedure in imperative languages like C
methods in OO languages like Java
and functions in functional languages like Haskell
◆ Functions return a value. So some purists would say that a C
function returning void is actually a procedure !
◆ Procedures are necessary for:
reducing duplication of code and enabling re-use
decomposing complex programs into manageable parts
◆ Procedures can call each other and can even call themselves
◆ What happens when we call a procedure?
The caller is suspended; control hands over to the callee
Callee performs the requested task
Callee returns control to the caller
There are situations, called hazards, that prevent the next instruction in the instruction stream from executing during its designated cycle
There are three classes of hazards
Structural hazard
Data hazard
Branch hazard

This Presentation describes the ARM CORTEX M3 core processor with the details of the core peripherals. Soon a CORTEX base controller(STM32F100RBT6) ppt will be uploaded. For more information mail me at:gaurav.iitkg@gmail.com.
found this one in one of my abandoned folders. AC(students from JUCSE need no introduction but for others you should never want to know him :-O) assigned this task to me and 3 of my fellow classmates to create a presentation on this uninteresting and weird topic. We pulled it off however :P
This provides information related to ARM Cortex-M4 features , Modes, Registers etc. I have discussed importance of multiple stack pointers and privilege levels. STM32 Nucleo-L4R5ZI board is taken for this case study.
Describes ARM7-TDMI Processor Instruction Set. Explains classes of ARM7 instructions, syntax of data processing instructions, branch instructions, load-store instructions, coprocessor instructions, thumb state instructions.

Comparison between RISC architectures: MIPS, ARM and SPARCApurv Nerlekar
Provides an overview about the three architectures, and if followed during any product design would lead us to choose a better architecture providing high performance of the product which ultimately means a leap in the market.
A short introduction on how functions work. Functions are the building blocks of any modern programming language. This tutorial shows you how functions are implemented and how the process stack plays an important role in supporting functions.

[cb22] Are Embedded Devices Ready for ROP Attacks? -ROP verification for low-...CODE BLUE
Yuuma Taki is enrolled in the Hokkaido Information University Information Media Faculty of Information Media (4th year).
At university he is focusing on learning about security for lower-level components, such OS and CPU. In his third year of undergraduate school, he worked on trying to implement the OS security mechanism "KASLR", at Sechack365.
Currently, he is learning about ROP derivative technology and embedded equipment security.
Parse::Eyapp is a collection of modules
that extends Francois Desarmenien Parse::Yapp 1.05.
Eyapp extends yacc/yapp syntax with
functionalities like named attributes,
EBNF-like expressions, modifiable default action,
automatic abstract syntax tree building,
dynamic conflict resolution,
translation schemes, tree regular expressions,
tree transformations, scope analysis support,
and directed acyclic graphs among others.
This article teaches you the basics of
Compiler Construction using Parse::Eyap to
build a translator from infix expressions to Parrot
Intermediate Representation.

Five cool ways the JVM can run Apache Spark fasterTim Ellison
The IBM JVM runs Apache Spark fast! This talk explains some of the findings and optimizations from our experience of running Spark workloads.
The talk was originally presented at the SparkEU Summit 2015 in Amsterdam.

ENERGY EFFICIENCY OF ARM ARCHITECTURES FOR CLOUD COMPUTING APPLICATIONSStephan Cadene
This thesis evaluates how the energy efficiency of the ARMv7 architecture based processors
Cortex-A9 MPCpre and Cortex-A8 compare in applications such as a SIPProxy
and a web server compared to Intel Xeon processors. The focus is on comparing
the energy efficiency between the two architectures rather than just the performance.
As the processors used in servers today have more computational power than
the Cortex-A9 MPCore, several of these slower but more energy efficient processors
are needed. Depending on the application, benchmarks indicate energy efficiency of
3-11 times greater for the ARM Cortex-A9 in comparison to the Intel Xeon. The topics
of interconnects between processors and overhead caused by using an increasing
number of processors, are left for later research
