Back in 1985 in response to the increasing density of then new electronics packaging technologies, test engineers from the major silicon vendors in Europe formed the Joint European Test Action Group and set about forming proposals for a new way of testing electronic devices mounted on a printed circuit board. In 1986 the group expanded [...]
Signal processing in ARM processor
Many applications that use an ARM processor as a controller also require significant digital signal processing performance. A typical GSM mobile telephone handset is a case in point; first-generation ARM-based designs typically incorporate a DSP core on the same chip as the ARM core, and the system designer has to make carefulchoices regarding which system [...]

ARM7EJ-S processor block, core, and interface diagrams About the ARM7EJ-S processor with Jazelle technology The ARM7EJ-S processor has the ARMv5TEJ architecture with Jazelle technology featuring an enhanced multiplier design for improved Digital Signal Processing (DSP) performance.The Jazelle technology enables direct execution of Java bytecodes on ARM processors, providing the performance for the next generation of [...]
JTAG Emulator for ARM
Embest UNetICE for ARM is the new-generation high-speed real time Jtag emulator made by Embest. UNetICE connects the PC USB port or Ethernet port to the JTAG interface of the arm target board and allows Flash programming and debugging. UNetICE allows you to: • Download target programs. • Examine memory and registers. • Single-step through [...]
ARM7 Microprocessor Family
The ARM7 core has a Von Neumann–style architecture, where both data and instructions use the same bus. The core has a three-stage pipeline and executes the architecture ARMv4T instruction set. The ARM7TDMI was the first of a new range of processors introduced in 1995 by ARM. It is currently a very popular core and is [...]
ARM Processor Fundamentals
Chapter 1 covered embedded systems with an ARM processor. In this chapter we will focus on the actual processor it self. First, we will provide an overview of the processor core and describe how data moves between its different parts. We will describe the programmer’s model from a software developer’s view of the ARM processor, [...]
