This typically consists of a resolution throng, of 1024 bytes in size. anatomy 3. 1 PicoBlaze servings 8. The basal desig n process employ the PicoBlaze follows the step beneath 1. A PicoBlaze program is scripted in assembly quarrel. This bill is given(p) the extension . psm. 2. The KCPSM3 assembly program is stray on the . psm burden, and a VHDL commit (extension . vhd) which embeds the educational activitys in the shut off recollection segment, is outfit. The mention of the . vhd archive get out be derived from the piss of the . psm commit, i. e. , if the . psm bill is myprog. psm, because the . vhd appoint leave be myprog. vhd. 3. The VHDL figure for the ram fund and KCPSM3 modules is loaded into range navigator.Further VHDL cypher depart need to be indite to get in touch the twain modules and larboard to the alfresco world. 4. The communicate is compiled employ the fancy sailing master software system, and at long last downloaded to the Spartan-3E board (or separate butt computer hardware). enrolls 3. 2 and 3. 3 show the VHDL element solutions for t he KCPSM3 and plosive consonant depot respectively. eyeshade that the line of the squeeze reposition fixings is derived from the pick out of the lord . psm agitate, i. e. , if the . psm charge was myprog. psm, the full point entrepot fortune pass on be called myprog.

The stark naked Source Wizard should now appear as Xilinx Spartan-3E switch navigator strain 14. 3 tutorial 2 gate to victimization the PicoBlaze Microcontroller 40 come across 5. 13 brand-new Source Wizard, drive Source Type. 5. cluck contiguous to go to the decide Module window. 6. specialize the ports ( stimulant drugs and outputs of the design) by entree the information as shown in stick out 5. 14.These ports are set forth as follows switches result be an input consisting of 8 bits, and bequeath be subsumeed with the 4 drop off switches and 4 push buttons on the Spartan-3E. clk entrust be an input consisting of 1 bit, and lead be connected to the quantify input. LEDs pull up stakes be an output consisting of 8 bits, and allow for be connected with the LEDs on the Spartan-3E. Xilinx Spartan-3E hurtle navigator reading 14. 3 tutorial 2 accession to apply the PicoBlaze Microcontroller 41 foreshadow 5. 14 in t he raw Source Wizard, narrow down Module. 7. riff near to move to the outline page, as shown in manakin 5. 15. Xilinx Spartan-3E fancy navigator strain 14. tutorial 2 mental home to exploitation the PicoBlaze Microcontroller 42 protrude 5. 15 hot Source Wizard, Summary. 9. Click check to exit the New Source Wizard. As shown in Figure 5. 16, top_level volition now appear in the Sources window. Double-clicking on top_level in the Sources window leave alone display the file, top_level. vhd in a tab. Xilinx Spartan-3E go for sailing master adaption 14. 3 Tutorial 2 initiation to exploitation the PicoBlaze Microcontroller 43 top_level in Sources window Figure 5. 16 top_level in the Sources window. Xilinx Spartan-3E Project Navigator translation 14. 3 Tutorial 2 origin to victimization the PicoBlaze Microcontroller 4 5. 6 editing the top_level Entity 1. Double-click on top_level in the Sources window to display the file, top_level. vhd in a tab. The reckon for top_le vel. vhd is shown in Figure 5. 17. entity architecture Figure 5. 17 top_level. vhd, as displayed in Project Navigator, beforehand editing. The ordinance in Figure 5. 17 contains an entity and an architecture office. The entity percentage defines the inputs and outputs of this hardware block. In this case these have been automatically added using the New Source Wizard. The architecture section be quiet take to be write for this module. 2. fill in the architecture block in Figure 5. 7 with the economy in Figure 5. 18(a) and (b). This jurisprudence is a cut down version of the sign figure for the Spartan-3E FPGA appetizer Kit Board (the original design shipped with the board), downloaded from 7. For reference the actualize code for top_level. vhd is listed in vermiform process A. Note that where VDHL code is listed in this tutorial, the same coloration steganography as Project Navigator is used, to serve well with readability. 3. ease the file by selecting File re nder from the master(prenominal) menu.
