Abstract & Project Goals המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 MicroBlaze is a Soft Core Processor developed by Xilinx that meets performance, area-efficiency and low cost targets. Although using the MicroBlaze enables fast system development on a single FPGA, some of the “special” applications run slower than in Hard Core Processor. We will examine this with EDK environment and try to accelerate the SW with hardware IP. Examination of MicroBlaze calculation abilities by measuring time of running applications and examining Interrupt handler abilities. Measuring power consumption by sampling current during program executions (LabView). Implementing arbitrary application in Hardware (IDCT) and using it as a hardware acceleration for MicroBlaze. Implementing the same functionality in C and comparing the results with hardware. Adding self written C code for testing FPU.

Distinguishing critical passes and implementing them in HW can greatly decrease execution time. FSL is the most effective (energy and time) way for connecting HW acceleration to MB. FPU is the most problematic consumer. Massive use of FPU is not recommended in MB. Interrupts input frequency is maximum 890kHz. Conclusions
