We analyse an impact of long-latency instructions, the family blocksize parameter, and the thread switch modifier on execution efficiency of families of threads in a single-core configuration of the UTLEON3 processor that implements the SVP microthreading model. The analysis is supported by code execution in an FPGA implementation of the processor. The conclusions drawn in this paper can be used to optimize code compilation for the microthreaded processor. As the compiler specifies the blocksize parameter for each family of threads individually, it can optimize the register file utilization of the processor.
