The design of the tranZPUter SW upgrades the Z80 hardware and canД¬lock the processor, detached from the Sharp MZ80A motherboard, at much higher clock rates, potentially to 20MHz using the Z8400 20MHz CPU. Of using a soft CPU is potentially better performance albeit this is yet to be determined as the K64F only runs at 120MHz. There is no real need to use the MZ80A memory when using a soft CPU. The program memory could either be that on the MZ80A or the faster K64F memory. To provide different CPU's it is just a matter of taking existing CPU emulators, for example those used in the PiCoPro and adapting them to use the CPU signals on the MZ80A bus via thisДesigns interface. The project adds the suffix SW for *S*oft*W*are to distinguish

ZPU Evo as the tranZPUter SW is more a software solution to the requirement rather than the ZPU Evo which is based on VHDL on an FPGA.

It uses a Freescale K64F ARM Cortex-M4 in place of the The tranZPUter SW follows on from the tranZPUter design in it's goals and makes an improvement on the underlying Z80 hardware at the same time. Sharp MZ80A by tri-stating the original Z80 and accessing the MZ80A memory and peripherals as though they were ZPU devices. The ZPU Evo provides the intended Menu, SD, Video Overlay services to the The tranZPUter gets its name from: A TRANsformable ZPU compuTER as the base CPU in the original tranZPUter is the ZPU Evo. The C/C++ control software written for the tranZPUter SW is intended to work on the tranZPUter under the ZPU.ДЄs the design replaces a Z80 in-situ it is not limited to the MZ80A but can be used in any Z80 based computer with the right software adaptations, ie. This design is a work in progress, working in tandem with the tranZPUter. Original speed when accessing the Sharp MZ80A motherboard peripherals.

The upgrade also extends the Z80 hardware capabilities by providing additional RAM to allow for a 64K version of CP/M and to increase the speed of the processor whilst maintaining the Where the original CPU is tri-stated and the K64F takes control of the bus and the underlying original mainboard peripherals, when needed. This is all made possible with bus mastering The machine with additional processing capabilities, storage and with multiple different CPU's based in software like the PiCoPro on the BBC Micro. To prolong the usage of the software but there is something special about using original hardware and this is an alternative to keep the machine original yet provide an upgrade that can power

Besides being part of history, it has a software base that is useful from time to time and still has followers. With modern computers (or a Raspberry Pi). It is vintage (albeit the Z80 is still widely used in new industrial designs clocking at 33MHz and above)) and under powered compared The Sharp MZ80A is based on the Z80 CPU running at 2MHz. Than enough general I/O pins and is 5V tolerant, hence this interim design (which is actually better for anyone who is a software programmer and is not happy with electronics or VHDL yetД®verything will be written in C/C++ (FLW - Famous Last Words - I had to write the interrupt service routines in ARM Thumb assembler as the K64F isnt quite powerful enough using compiledД¬) and once working, I can take the bold step into speccing a tranZPUter v2.0 with a BGA knowing that the ZPU will run all the software just written. Happy about soldering a 30+ pound IC where only an X-Ray machine can validate that it was soldered correctly, I opted for a powerful mini-development board, the Teensy 3.5 which has more KISS comes back to mind, Keep It Simple Stupid! So in order to further the conceptДЄnd design I took a step back, looked at what was needed at the Z80 side to realise the CP/M requirements and looked at what was needed for the controlling IO Processor. This meant that multiplexing had to be used with tri-state register latches. This device and all other possibilities for the given size and FPGA ALM requirements had IC's, I chose the next best thing, a pre-fab FPGA board, the CYC1000 with the FPGA already soldered. V1.0 of the tranZPUter had design restrictions which in all honesty make the project much harder to complete, for example, because of my lack of experience soldering BGA (Ball Grid Array) It should also run independent of the controlling IO processor, ie. The tranZPUter SW is an offshoot from the tranZPUter project and utilises a Freescale K64F processor as the IO Control processor as opposed to the ZPU in the original tranZPUter project.Дuring testing of the tranZPUter v1.0 and with the advent of the RFS v2.0 upgrade with CP/M it was noticed that the tranZPUter should be updated so that the Z80 had additional memoryДЄnd was able to run at higher clock frequencies. The tranZPUter and tranZPUter SW are actively being developed and changes are reflected in the documentation on a regular basis.
