May 3, 2011 -- SingMai Electronics is now offering its PT13 compact MPU IP core as a free download for users of Altera programmable logic devices. The PT13 is a compact 8 bit microprocessor that uses just 374 logic elements allowing its use in the smallest of FPGAs. Its compact design extends to a register based stack pointer that allows a ‘RAM-less’ design to be implemented, ideal for CPLDs.
PT13 can address up to 16kB of program memory and 16kB of user memory or memory mapped I/O peripherals and has over 45 instructions. A free editor and assembler allow easy generation of code which is directly compiled into an Altera MIF file for compiling directly into your design.
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.
PT13 is supplied as an encrypted 'black-box' file at no charge to Altera users. Please contact SingMai at firstname.lastname@example.org for your free license and design file.
