Enhanced DSP instruction set support Supports an extended set of DSP-related functions, such as saturating arithmetic and Single Instruction Multiple Data SIMD vector-style instructions, for example adding two bit registers as four parallel 8-bit additions tdm than a single bit addition.
TDMI maintains DigitalData saves contact centers money by automating data collection, which the company says will help eliminate typos and lost opportunities due to incorrect information while decreasing the costs associated with transcription.
The debug extensions provide the mechanism by which normal operation of the processor can be suspended for debug, including the input signal ports to trigger this behavior; for example a signal to allow a breakpoint to be indicated and a signal to allow an external debug request to be indicated. Moreover, different compilers may generate different kinds of symbolic debugging information, which Bound-T uses to communicate with the user in source-level terms.
What does “TDMI-S” stand for?
ARM offers a variety of licensing terms, varying in cost and deliverables. If the BX is used only to change state, the target address is very probably a constant that can be deduced from the analysis, giving an automatic analysis of both the branch and the change of state. Wikipedia gives some background and useful links.
In this sense, it can be considered a prototype implementation.

ARM Microcontroller HOWTO: Introduction to ARM7TDMI core
Enhanced relative to earlier ARM cores 32×8 Multiplier block. Some compilers generate “interworking” code by default, others may need a specific compilation option or directive to do so.
The meanings of ‘TDMI-S’, ‘JZF-S’ and ‘T2F-S’
Technical documentation is available as a PDF Download. See also the general Bound-T manuals. In principle Bound-T is able to analyse machine code from any compiler. In it was one of the most widely used ARM cores, and is found in numerous deeply embedded system designs.

The EmbeddedICE interacts with the debug extensions, for example to signal a halt to the processor when a breakpoint is met. ARM bitThumb bit. Submit Rating and Feedback. Subsequently, demand increased for a more flexible and configurable solution, so ARM moved towards delivering processor designs as a behavioral description at the “register transfer level” RTL written in a hardware description language HDLtypically Verilog HDL.
This was the prevalent design methodology at the time. This allowed more distinctive features to be represented in the suffixes of ARM11 processor names without the name suffixes becoming too cumbersome.
However, different compilers create executable files in different formats, and Bound-T is not able to read all possible formats. Views Read Edit View history.
TDMI is hoping to help companies currently employing point-of-sale systems, call center systems, CRM packages and IVR applications by providing instant access to new customers’ contact information.
For these reasons, Bound-T often needs to adapt its analysis to the arj that generated the code to be analysed. To improve code density, a new, smaller instruction set called “Thumb” was developed, implementing the more commonly-used parts of the ARM instruction set but encoding these in a bit or 2-byte pattern or occasionally, a pair of such opcodes.
To determine which components have been included in a particular ARM CPU chip, consult the manufacturer datasheet and related documentation. The processor can switch between the two instruction sets at run-time, using the BX “branch and exchange” instruction to change from ARM state to Thumb state or vice versa.
Finally, each compiler may generate its own idiomatic instruction sequences, some of srm need special analysis methods, and has its own set of library subprograms, some of which may not follow the ordinary parameter-passing and stack-handling rules and therefore need special attention in Bound-T.
The EmbeddedICE macrocell consists of on-chip logic to support debug operations. This instruction set ram is called ARMv4T. Supports the Thumb-2 technology extension Extends the original Thumb instruction set by adding more double-opcode instructions, to enable a complete system to be implemented using only Thumb instruction mode.
