At the heart of contemporary embedded solutions are systems on chip (SOCs) with millions of gates, integrating cache, scratchpad random access memory (RAM), and peripheral functions onto one chip; ...

Remote-controlled through the JTAG interface or some other debug interface, the processor core uses write and read access to the system bus with respective test vectors in order to manipulate and test ...

A new embedded debugger is the first in system JTAG based debugger for Intel x86 platforms. According to Asset InterTech, the debugger implements hardware based run control in system firmware.

While the scope of this paper is JTAG and software debug, another white paper, Designing Embedded Systems for Debugging and Testing (PDF) covers some of these other topics.

Taken literally, embedded test is just that: test capabilities that exist wholly embedded within a system. Power-on self-test is an example as is a built-in performance-monitoring feature ...

Next, came the support for in-system programming of CPLDs (Altera, Cypress, Lattice, Xilinx etc) and then parallel flash memories. It was at this stage in the development of JTAG technology that PCB ...

Lauterbach and Gleichmann Electronics Research will demonstrate at Embedded World 2010 next month a new way of debugging CPUs that are embedded in programmable logic. The JTAG–based technique combines ...

Generically, embedded test implies a test capability that has been integrated into a product. Of course, whether that product is an IC, a PCB, or a complete system, embedded test ...

Cambridge, UK A UK company has developed a JTAG debug scheme that reduces the number of device pins required for debug from five to one. Debug Innovations' J-LINK system was architected and designed ...

JTAG provides a simple and well understood interface supported by many embedded systems tools vendors. JTAG, as IC and board level test interface, has limitations when used as an instrumentation ...

System ACE works on the JTAG chain like an external debugger through the debug port of the processor. Code, data and, if required, a RAM disk, for the Linux kernel are loaded through the JTAG chain ...

The JTAG Connection The Internet of Things will contain billions of “intelligent” devices. Each of them will be a potential security risk.
