hey everyone i need help finding the solution to the single-cycle and muti-cycle MIPS processor using VHDL code. i've worked on it for 5 days now and no luck. someone help me if they can find me some VHDL files. see ya
Hello everyone, Can antone please help me in understanding this instruction logic of the single cycle processor. I am confused at some points. what's the input to the program counter? The output to the program counter is going to the instruction memory. But I am confused about the input stage. I read the theories from the book by David A. (...)
There are many Harvard microcontrollers, DSPs are mostly Harvard, but the key advantages of DSP are: - most instuctions are single cycle, and 16 or 32 bit devices; - supports special instructions for signal processing: multiplications, multiply and accumulate the result (MAC) in 1 cycle, data adjusting, representation conversion; - (...)

hey , i hav made my single cycle mips code in verilog HDL now i hav 2 check my processor for results...can u plz help me out abt what are the steps now ? n simulation tools required ...i don't know how 2 write assembly code 4 it plz. do provide some examples ...thanx
All of the three options are correct. Internal register width, determines number of bits a processor is capable of handing at a time. Register width in turn dictates data bus width, and number of bits ALU can process in single go. 8-bit processor can very well process 16 & 32-bit data, but not necessarily in a single (...)
Hi I need to decide which CEVA DSP processor to use to incorporate in a digital hearing aid But I am not sure how to choose the right one seems to be the most popular one for hearing aids and it is the only one listed in the website that
Its not a easy question to answer, it depends entirely of which processor you are using. You have to search in the datasheet/manuals for the specific processor you are interested in. Most of the manufactures specify how many clock cycles is takes to execute an instruction. For the Coldfire for example, you find this information in the (...)
The clock frequency is devided by 2 inside the 8085 microcontroller .. Frankly, I don't recall any advantage of deviding the clock frequency, and it is more like an artifact of the 8080 arangement, where the latter used to use 2-phase clock, generated by an external clock IC, the 8224, to perform reading and writing cycles using another external
hi there, please help me with a clear explanation about machine cycle related to the second, please give me the equation, and then about the clock. Firstly, you should know about clock cycle, which is the highest frequency component in the processor, and is used as a basis for all other operations. An instruction cycle (
Hi, I would look at least at three different companies about 8051. If you need the fastest and best analog features, look at Silabs. They have a great variety with some exceptional features, outperforming any other 8-bit architecture I know with 100 MHz single cycle devices. If you need more "standard parts" and top performance is not as imp
PacoBlaze is a from-scratch synthesizable & behavioral Verilog clone of Ken Chapman's popular PicoBlaze embedded microcontroller. KCAsm is a lightweight PicoBlaze assembler written in Java. While Ken's version aims toward the most efficient implementation in the Xilinx FPGA architecture, PacoBlaze tries to be as configurable as possible, maint
Who can modify the HDL code for the single-cycle MIPS processor to handle SRA(shift right arithmetic)...?? ------------------------------------------------------------ -- mips.vhd -- and 30 May 2006 -- single cycle MIPS processor -----------------------------------------
As far I know I don't think that you could find a faster way to test the status of a I/O line using a commercial CPU: usually the status of processor's IO line is mapped to a specific bit in one (or more depending on the IO pin count) CPU register. So I suppose that 2 clock cycles are the minimum overhead you could expect to acquire this informatio
Hi I need a implementation datapath and controller for MIPS instructions(R-type and I-type instructions) in single cycle with verilog code,can u help me ?
plz any one help to modify the MIPS single cycle processor for lui and shift instructions. or any one have any link related to that.
Hi everyone. I have a college work where I have to use a VHDL file that was given to me. But whoever made this file used std_logic_arith. So I went and converted it to numeric_std. So far so good, but now I had to add some content, and it's failing to work. I have to use the SLL operator with std_logic_vector. I know it's not ideal, but it wo
Duty cycles can be measured with input capture unit by determing both low and high period, but only within the timing resolution given by the processor clock. Duty cycle infomation at 1 MHz will be respectivly coarse. Outputs of ATmega are exclusively digital (0/1), so I wonder how you want to output the duty cycle by a (...)
So which one is better, 1GHz dual core or 2GHz single core? Depends on your application. If you're just doing a single task a 2GHz single core would be faster. If you're multitasking, the dual-core would probably be faster.
"The P89LPC932 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC932 in order to reduce component count, board space,
has anyone implemented the PHY itself as software ? It's a chalenge for you at 2.4 GHz. Why don't you try what is already done in the market ? You have an 2.4 Ghz IEEE 802.15.4 compliant RF transceiver and 32 MHz syngle-cycle low power 8051 MCU with 128 kByte in-system programable flash and 8 kByte SRAM in a single
you can even consider a VLIW processor architecture in which a single clock cycle is enuff to execute a multi-op which has several instructions clubbed together. well as for the clock generated it has to be double the internal clock frequency for the fact that lots of spatial variations could be encountered.. so as to avoid that external (...)
Hi ed271828. It is possible to purchase the XT-2000 prototyping board. There is a Virtex-2P for a single core implementation, and another FPGA for custom hardware. Every time a new core is generated, a new synthesizd encripted core is provided. The core is ready to support the Xilinx design flow, so you can you ISE. I hope it will help you
wajahat, DSPs are optimized for speed and DSP. For example, most DSPs execute all their instructions in a single machine cycle. Also, DSPs have instructions specifically designed for DSP, such as "MAC" (multiply and accumulate) which execute in a single machine cycle. Regards, Kral
hi pradeep, MAC in DSP is Multiply and accumulate in a single clk cycle. chin
U can easily design it using memory mapped I/O ... It can have a max of 64K ports in 8086....because single bank can have max of 64k....

Originally the JIFFY was the time interval between system timer interrupts, however today it's referred to as the software clock and based on the kernel variable HZ. The value of HZ ranges from 1ms to 10ms, depending on the speed of the processor with 4ms being the default. JIFFIES is the running count of each JIFFY. The kernel offers two delay
Many times we require precise internal time delays between two actions this can be accomplished using software techniques like Loop Technique but these delays keep the processor occupied because of which other important functions cannot be done. To relieve the processor of this burden we can use TIMERS provided by the controller. 8051 has two inter
Ok, so assume we have a MIPS-like ISA, such as the one from MIPS R3001. In this, assuming registers are already available, an addition is computed using a single instruction as follows: ADD R1,R2,R3 where R1 is the register where the result will be stored, and R2 and R3 are the source registers. Now, the execution of the instruct
DC-bus current ripple depends on load inductance and PWM scheme (2-level or 3-level), but will be generally high for a single phase H-bridge. Assuming sufficient load inductance and preferable 3-level scheme, the DC-bus "sees" the 30 A motor current switched on and off, resulting in 15 A rms ripple current at 50% duty cycle.
