CPI Rd,k;CompareregisterRd with a constant k Example LDI R16,15;LoadregisterR16 with a value15CPI R16,10;Compare R16 with10 Conclusion In this chapter, we provided a detailed explanation on different logical instructions in AVR microcontrollers. These instructions are very important for manipulating...
The microprocessor controls execution of all the operations of the microcomputer, such as data storage and retrieval, arithmetic, and logical instructions. It does so by manipulating a certain number of bits (units of information) at a time--usually 8, 16, 24, or 32. Tips on buying microcomp...
Mechanism to assign more logical load/store tags than available physical registers in a microprocessor systemA method of handling instructions in a load/store unit of a processor by dispatching instructions to the load/store unit, filling all physical entries of a reorder queue with tags ...
Today, Intel and AMD are two major vendors in the microprocessor industry, each with their own line of CPU architectures. The x86-64 CPUs from Intel and AMD, basically emerged as CISC architectures, now incorporate a number of RISC features, especially to provide forInstructions Level Parallelism...
