Table 1a: The complete MSP430 instruction set of 27 core instructions core instruction mnemonics core instruction . The addressing bits responsible for the addressing mode used for the destination (dst). D-reg The working register used for the . It will take 5 cycles of CPU clock to execute. Instruction 3: To assemble the
The execution of an instruction includes several memory operations and not all instructions execute the same number of memory operations. Furthermore internal processing of some instructions requires more clock cycles than others. On the MSP430, each memory operation requires one clock cycle. Thus, you should not
The Family Reference Manual has timing info for various instruction starting on page 63. The number of cycles MSP430 Instruction timing. I haven't used an MSP4340, but I imagine there should be a tool available in the IDE to time your code and tell you how many cycles it takes to run. I'd try and find/use

The MSP430 has a register file with 16 registers (R0-R15) that are all visible to programmers. Register R0 is reserved for in Figure 1. Register-register operations are performed in a single clock cycle. . The core instructions are instructions that have unique op-codes decoded by the CPU. The emulated instructions are
Reading the datasheets for the MSP430, it gives a 125 ns Instruction cycle time. The User's Guide seems to suggest an *average* of 4 instruction cycles for a given operation. Atmel's AVR datasheets say that most instructions take place in 1 cycle.but how long is this cycle? It seems to me that although the
The msp430 is a 16-bit system, so 32-bit values are not supported directly. A 32-bit operation is typically translated to assembly code as a sequence of 16-bit ops. The execution times of 8-bit and 16-bit operations can be found in TI application report "The MSP430Hardware Multiplier": Table 4. CPU Cycles
24 May 2011 When we're working with microcontrollers or programmable systems, one aspect, we must have very present, is the time that our code, function or piece of code consumes. Why is it important? For many reasons, for example: Synchronizing with any extern device, managing a communications bus (I2C, SPI,

If you are interested in just one or two functions, the profile clock would be the simplest and easiest way to count cycles. Thanks. ki. -----------------------------------. Did you read
