There's more… To understand how the processor achieves this level of performance, we need to look at the processor architecture. com. ARMv7-M is a 32-bit architecture and the internal registers and data path are all 32-bit wide. ARMv7-M supports the Thumb Instruction Set Architecture (ISA) with Thumb-2 technology that includes both 16 and 32-bit instructions. ARM processors were originally inspired by Reduced Instruction Set Computing (RISC) architectures developed in the 1980s. RISC architecture attempted to improve on the performance of traditional computer architectures of the era that employed the so-called Complex Instruction Set Computing (CISC) architectures, by defining an ISA that supported a small number of instructions, each of which could be executed in one processor clock cycle, and so achieve a performance advantage.
The ball direction is changed accordingly when a collision occurs.
UVision5's RTE manager includes a suitable API, but this provides many more features than we need for our simple helloWorld recipe. c shown in step 4 and step 5 that ARM shipped with uVision4. c comprises three functions SER_Init(), SER_PutChar(), and SER_GetChar(). The function SER_Init() is the first function called by main(). It initializes the USART peripheral by writing values to its registers so that it is configured to mirror the channel setup in PuTTY (that is, 115200 baud, 8 data-bits, 1 stop-bit).
