Last month, YouTube debuted the Cosmic Panda experiment, a massive redesign of the site, the biggest in its history, which borrows some elements from the common design direction at Google.
One distinctive feature of the new design is the new black player and Google is now rolling out an embedded version of it. The new black embedded YouTube player is identical to the one in the Cosmic Panda experiment and looks rather slick.
While it's similar to the older and still used embedded YouTube player, it does look more refined and polished.
Considering that the current player looks rather snazzy itself and that YouTube is hardly a small site which can't afford a great designer, the fact that there is a noticeable difference in the quality of the new design speaks volume.
There are four color variations of the new embedded YouTube player, there is the default black player with a red progress bar, a black player with a white progress bar as well as the same to version with a white background.
This property specifies or retrieves a value indicating whether the Windows Media Player control automatically resizes to accommodate the current media item at the size specified by the DisplaySize property.
1 - Width and height are one-half of the source image dimensions, resulting in an image that is one-fourth the original size. This property acts as a multiplier value that allows you to play a clip at a faster or slower rate. The stretchToFit property specifies or retrieves a value indicating whether video displayed by the Windows Media Player control automatically sizes to fit the video window, when the video window is larger than the dimensions of the video image. The project consists of a custom 32-bit soft core processor running at just under 60MHz which decodes the MP3 algorithm in software with no hardware acceleration apart from a single cycle Xilinx multiplier unit. The FPGA-Audio project hardware simply consists of a Xilinx Spartan 6 FPGA with supporting components (2xVREGs & SPI-PROM), asynchronous 512KB SRAM, 24-bit Stereo DAC & Micro SD socket. Additional connectivity is available via a ‘UEXT’ connector, a 10-pin expansion connector that can be used to connect to various modules provided by the popular Olimex Ltd (see here…). The FPGA can be used to instantiate UARTs, SPI & GPIO (or other) interfaces to this connector in any chosen pinout.
This interface will in the future be connected to another custom board with a display, buttons & IR receiver to enable control of the audio player.
The aim was to create a minimal design where as much functionality as possible was realized internally in the FPGA.


By not including native multiplication & division instructions, the pipeline is simplified and the core is smaller. Multiplication & division is provided by replacement functions in the C library (mulsi3, divsi3, etc).
Note: GCC was modified to provide the option to disable the MIPS mult & div instructions as well as to enable turning off the patented unaligned memory access instructions.
MPX can execute 1 instruction every cycle except for memory access instructions which take 2 cycles (see below). As the architecture has a branch delay slot, knowing that you will branch in stage 2 means that you will have also already scheduled a instruction fetch for PC+4 in stage 1, meaning you do not have to flush any part of the pipeline on a branch operation. As MPX is currently a Von-Neumann architecture, memory access instructions cause a ‘bubble’ instruction to be inserted into the pipeline.
The current implementation of MPX in the FPGA-Audio project does not make use of caches; internal memory is tight on the FPGA and can be better used for audio FIFOs & SD DMA buffers than for a cache. MP3s with a bitrate of 320Kbps (stereo) use around 96% of CPU time, but the 4% of free CPU cycles is enough for the decode task to produce more data than is consumed.
This extra data is stored in a queue of audio buffers to be loaded into the 2K audio FIFO by the I2S driver when space is available.
WAV files skip the going through the MP3 decoder, instead data is loaded from the file system then fed straight into the audio FIFO which is expecting 16-bit stereo PCM data. This 3rd party C library provides MPEG compliant decoding of MP3s and the version used is a fixed point implementation that was optimized for ARM CPUs. The port of this software to MPX requires no assembly optimization; the system is fast enough to execute the algorithm without rewriting any sections in ASM. FPGA-Audio uses a 32?32 hardware pipelined multiplier block created via Xilinx ISE’s Coregen which provides a 64-bit result in 1 cycle using the Spartan6’s DSP48 slices.
The hardware multiplier unit is key to being able to play high bit-rate (or even low bit-rate) MP3s in real-time due to the vast number of multiplications done as part of the MP3 decode algorithm.
At the lowest level, the SD card is accessed in SPI mode, where file system data is loaded into a dual-port RAM block using DMA from the SPI-Master peripheral. Upon transfer complete, and interrupt is generated so that the software can continue doing more useful things than polling for SPI transfer complete.


The dual-port RAM block is memory mapped so the processor can quickly access & manipulate file data in-situ.
The RTOS was written mainly in portable C with a small amount of assembly code for CPU specific context save & restore.
In this system, the RTOS is pre-emptive with a 1ms tick time, and features support for interrupts, mailboxes, semaphores & mutexes.
SD card access is also interrupt driven meaning that no polling of peripherals is required in the project. In addition to the instruction set simulator, the RTL code was used with Verilator which is an open source tool that allows Verilog to be compiled to a C++ model. The ‘Verilated’ model could then be used to execute code in a cycle accurate way (with peripherals) and also be run in tandem with the instruction set simulator to allow for co-simulation.
There is an app note on this subject by Microchip using the same decoder library, so yes you can! Check out this neatly home-built dual player arcade machine powered by Raspberry Pi from rolfebox.
Check out these free comprehensive tutorials and DIY projects that are intended to facilitate the learning of chipKIT interfacing and programming. The name is derived from the fact that it implements the majority of MIPS-I ISA, meaning that it can make use of an existing GCC port for MIPs architecture (MIPs is a trademark of MIPS Technologies which I am in no way affiliated with). Obviously, in this case you would need to have autostart enabled or there will be no way to play the video.
I would like to evaluate the cost of assembling one, I’d like to try the Spartan 6 for other study project and your board is just great.
