PT13

PT13 is an embedded microprocessor IP core intended for simple control operations.

Many applications would benefit from a small degree of local ‘intelligence’ and PT13 is designed for that very function. Whilst most available microprocessor IP cores require external FLASH memory and even external data memory, PT13 is optimized to be completely embedded and use as little FPGA resources as possible.

PT13 uses just 316 logic elements and as little as a single 4kbit ROM block, allowing it to fit in the smallest of FPGAs or even permit multiple instances in the same FPGA.

Yet PT13 can address up to 16kB of program memory and 4kB of user memory or memory mapped I/O peripherals and has over 45 instructions. An editor and assembler allow easy generation of code which is directly compiled into the FPGA download file.

PT13 is ideal in real time control applications allowing such functions as TV tuner control, I2C control, RC5/RC6 decoding, LCD display control, user interface control, closed caption/Teletext decoding and general housekeeping duties to be run without burdening the main control processor. These functions can also be run in very low power applications such as STB/DVD recorder standby conditions or mobile applications.
