ARM is entering the digital signal controller market with the Cortex-M4, a 32-bit core with built-in integer DSP, and an optional floating point unit. The processor is aimed at applications in audio, ...

Pipelines. ARM7 has a three-stage pipeline; stages being fetch, decode and execute. Cortex-A8 has 13 stages. Co-processors. Co-processors are used to extend the instruction set. The co-processor space ...

The latest processor from ARM is the Cortex-M4 that has been unveiled for digital signal control markets. The processor promises high-efficiency signal processing with low-power use, low cost, and ...

Current Arm cores use either the Thumb instruction set, for applications that require densely packed code, or the ARM instruction set, for performance needs, but Thumb-2 will allow chip designers ...

Rather than use the Cortex-M4 core, Texas Instruments has opted to integrate its own higher performance C28x DSP core with an ARM Cortex-M3 core. The Concerto F28M35x microcontroller series, announced ...

The M7, we're told, has twice the DSP power of the M4 by executing twice as many instructions simultaneously, and it also helps that the M7 can operate at a higher clock frequency than the M4. "The ...

There are many signed multiply instructions that are not available in Cortex –M (These are DSP instruction set Summary). These DSP instructions are available in Cortex-M4.

Thumb-2 instructions provide code density while maintaining the performance of standard ARM code; Jazelle RCT technology does likewise for realtime compilers. TrustZone technology provides security ...
