Archived from the original PDF on I'm doing something similar in my current design. It is not possible to implement computed jumps or function pointers.
Anyway, life could be better if I can use a verilog version of PicoBlaze directly. Views Read Edit View history. This does not preclude the use of a Forth -like data stack, and in fact the PicoBlaze is well suited xilnix this approach, if the byte scratchpad memory offers sufficient space. This is an unfortunate side effect of maintaining compatibility with the widest number of development computers and with the original choice of programming languages to create the KCPSM3 assember.

From Wikipedia, the free encyclopedia. However, you still need to adjust the register assignments for the upper 16 registers.
The instruction sequencing side does not contain an adder, so relative branches and position independent code are not possible. Picoblaze3 has 16 registers vs 32 for Picoblaze2. On Thu, 17 Jun The problem seems to be that kcpsm3 doesn't accept register names of the form 's00', which is the only form that kcpsm2 accepts.

Either way, check out page 69 in the following document. Sign in Sign in Remember me Forgot username or password?

Reduced instruction set computer RISC architectures. Also PacoBlazea behavioral and device independent implementation of the cores exists and is released under the BSD License. No, a Verilog version doesn't exist. The only information which flows from the sequencing side to the execution side are operand fields: Also, you should use picoblaze2 if you can; the extra code space helps.
Introduction to Microcontrollers Mike Silva. If you write one, let me know! I contacted Xilinx about this and they said that it wouldn't be fixed.

The assembler doesn't correctly handle source files if they have names longer than 8 characters, or if they are in a directory other than the directory containing the assembler, or if they are not in the current directory.
One alternative is to use the more modern Mediatronix pBlazIDE graphical development environment, which is also no charge.

Some bugs in kcpsm2. The license of the cores allows their free use, albeit only on Xilinx devices, and they come with development tools.
The latest PicoBlaze design is available from the following site.
