MIPS, once a formidable competitor to ARM in the microprocessor field, had its golden era. However, in the mobile domain, MIPS gradually fell behind, and its academic development style significantly lagged behind ARM’s commercial progress. How many people still remember MIPS today? Just when it seemed that MIPS was about to fade into obscurity, Imagination … Read more
A single board computer (SBC) integrates a microprocessor, memory, and interface components onto a single printed circuit board. Typically, each single board computer includes a CPU, GPU, chipset, and I/O ports, all soldered onto the board. Because the components are all on one board, single board computers are much smaller compared to most other motherboards. … Read more
Source: DigiKey 1 Choosing the Microprocessor for Embedded Systems Every electronic system requires a microprocessor (MPU) core; some systems may opt for microcontrollers (MCU), digital signal processors (DSP), field-programmable gate arrays (FPGA), or single-board computers (SBC) to handle the computation and control tasks. Below is an overview of microprocessors and related products. The Microprocessor is … Read more
