This virtual processor allows the user to write programs in machine code for it ... if I is not set or a 14 bit address if I is set. Three instructions exist for branching, BRN, BRNL, and RET. Both ...

If instruction sets didn't matter, processors would be cheaper and designers would have more options. That's why one startup's efforts are so intriguing. Every microprocessor is different, in part ...

Low-cost 6-stage pipeline of an 32-bit RISC-V processor allowing the dual-issuing of only 16-bit compressed instructions. DRiM can substantially improve instruction throughput and reduce execution ...

Thumb-2 technology adds about 130 additional instructions to Thumb. The added functionality removes the need to switch between ARM and Thumb modes in order to service interrupts, and gives access to ...

Custom instruction-set architectures, or custom ISA extensions ... You can start your work with a full-blown RISC-V-compliant processor and add custom ISA extensions according to your needs, or you ...

This chapter presents the key characteristics of the first generations of microprocessors or microprocessor unit. It discusses the 4‐bit family ... The first is called reduced instruction set computer ...

The Intel 8088 (and its big brother 8086) processor was among the first microprocessors to implement (instruction) prefetching in hardware, which [Ken Shirriff] has analyzed based on die images ...

Is it small enough to replace 8-bit processors? What might help people migrate to a more modern processor architecture? RISC-V defines a 32-bit processor instruction set architecture (ISA) that is ...
