ARM vs. DSP vs. FPGA: Main differences between them

What is ARM? A well-known manufacturer of microprocessors, ARM (Advanced RISC Machines) is responsible for the design of numerous high-performance, low-cost, low-power RISC CPUs, as well as associated hardware and software. The ARM architecture, which offers a variety of cores, system extensions, microprocessors, and system-on-chip solutions, with four functional modules available for manufacturers to configure production according to the needs of various users, is the first RISC microprocessor created for the low-budget market. It is essentially the industry standard for 32-bit microcontrollers. The same software can run in all products since they all share a common software architecture. Since ARM presently controls more than 90% of the handheld device industry, it can significantly speed up application development and testing while simultaneously lowering R&D expenses.
