You are on page 1of 6 Search inside document Introduction to using PicoBlaze microcontroller with the Nexys3 board This laboratory work is a guide for the PicoBlaze first time users. The objective is to present basic information about the PicoBlaze microcontroller and to describe the basic steps that have to be made in order to implement a very simple project and download it to the Nexys3 board. Figure 1. All instructions have an 18 bit format and are executed in 2 clock cycles. The maximum clock frequency depends on the device and the design.

This status of the flags can be used to determine the execution sequence of the program using conditional and non-conditional program flow control instructions. JUMP commands are used to specify absolute addresses aaa within the program space.

The stack supports up to 31 nested subroutine levels. The program will execute from address and interrupts will be disabled. Note that register contents are not affected. The port address can be specified in the program as an absolute value pp , or may be indirectly specified as the contents of any of the 16 registers sY.

During an INPUT operation the value provided at the input port is transferred into any of the 16 registers. It is not always necessary to use this signal in the input interface logic, but it can be useful to indicate that data has been acquired by the processor. This strobe signal will be used by the interface logic to ensure that only valid data is passed to external systems. Scratch Pad Memory This is an internal 64 byte general purpose memory.

The contents of any of the 16 registers can be written to any of the 64 locations using a STORE instruction. The complementary FETCH instruction allows the contents of any of the 64 memory locations to be written to any of the 16 registers.

The 6-bit address to specify a scratch pad memory location can be specified in the program as an absolute value ss , or may be indirectly specified as the contents of any of the 16 registers sY. Only the lower 6-bits of the register are used, so care must be taken not to exceed the 00 - 3F16 range of the available memory. Simple logic can be used to combine multiple signals if required.

Microblaze design Integrated software Development Kit Does the MicroBlaze core support user- defined instructions? PicoBlaze provides 16 8-bit registers and executes one. Embedded Design Using Programmable Gate Arrays ; This text is intended as a supplementary text and laboratory manual for The FPGA has traditionally provided support for embedded design by Because the LCD timing is very slow, with some instructions requiring up to 1.

This time, Vivado should successfully place the design. Xilinx architectures are column-based, meaning that every tile or resource type is the same for a column of the device layout.

Consider the device floorplan view below where major tile types have been highlighted: Tiles of the same type have all of the same logic and local interconnect and are repetitive in their respective columns.

The main constraint for the PicoBlaze is a block RAM and we can leverage RapidWright to help us analyze the fabric to find the most repeated tile column patterns adjacent to block RAMs.

To do this, in our terminal open the RapidWright Python interpreter by running: java com. RapidWright Then in the terminal we can use a class called TileColumnPattern to analyze the fabric and create a map of all the tile patterns in the device.

BRAM in e. The BRAM appears in tile columns indices 75, 97, , … as shown in the image below: Note that the tile column numbers appear much higher than what would be expected based on the number of visible columns.

This is expected as there are several tile columns not necessarily shown in the Vivado GUI, but RapidWright is able to filter and account for the non-visible tiles.

DSP in e. To help visualize the pattern, here is the first instance index 94 outlined in the previous floorplan view above with the highlighted tiles: The second match is a juxtaposition of the first pattern and covers the same columns note the indices are very close to those of the first.

The third, forth and fifth are also juxtapositions of each other but cover a unique set of BRAM columns not covered and one of them will cover 3 more unique BRAM columns. Therefore, the final BRAM column , can be covered by the 6th, 7th, 11th or 12th pattern.
