I am told to design a generic microprocessor interface for a ASIC chip. Since I am not familiar with what types/modes of microprocessor are most popular, I don't know how generic I can reach. I am aware of there are synchronous/asychronous modes, separate or mux address/data modes. But I notice there are so many different families and series. Would somebody point me some typical familie...


GPIO : Reading when configured as O/P

Hi, I am currenly integrating an 8051 soft core into our ASIC and we have a number of GPIO ports (which are placed in the bit addressable SFR space). When a bit of the GPIO port is configured as an O/P 1 - Any write to the bit appears on the pin (obviously) 2 - A read of the bit returns the current value *at the pin* Item (2) seemed to make perfect sense when performing the design (an...

I am getting ready to begin my first project using an ARM core. We are porting embedded software from an existing product that uses a Motorola 56311 DSP to a new design that uses an ARM 966E-S based ASIC. I am in the process of choosing the compiler/toolset that we will use for this project. I have narrowed my list down to the RealView Developer Suite from ARM and MULTI from Green Hil...

Version 3.1 of Tyd-IP Code Generator has now been released. Now supporting multirate filter design, designers can create a wide range of IP, including filters, FFTs, NCOs etc. which can be targetted at any FPGA or ASIC. Until, the end of May 2007, the multirate coefficient and VHDL module, will be available free of charge to all purchasers of Tyd-IP. Regards Robert


Emulating 1-wire interface with a microcontroller

Hi, I have a microcontroller with GPIO, I2C and UART, and I'm trying to emulate a 1-wire interface so that the microcontroller appears as an i- button to another ASIC. I'm wondering if it would be easier to use either of the serial channels(UART or I2C) or should I just emulate it with GPIO? Would also appreciate any tips/help on how to emulate, and 1-wire standards, since I'm new to 1-...

Please tell me what is the cheapest ARM with my request ip. Our company would like to change current audio application to embedded system. after my researching, only 2 way to realize, one is made ASIC Chip (request very long develop time,and huge investment), another is buy ARM with specify IP Core. Requirement for our Audio system: MP3 decode/WMA decode CD/MP3 CD/WMA CD decode includin...


ARM7 vs. ARM9 (system power consumption)

We are trying to decide on whether to use ARM7 or ARM9 core in a ASIC design. One major consideration is system power consumption. From what I am told, the ARM9 consumes twice as much power as the ARM7, but most of this extra power is used by the cache. It is hard to believe that the cache controller consumes this much power, so I have to assume that the cost includes the power used by t...
