applications. The device consists of four xCORE Tiles, each comprising a flexible multicore microcontroller with tightly integrated I/O and on-chip memory. The processors run mutiple tasks simultaneously using logical cores, each of which is guaranteed a slice of processing power and can execute computational code, control software and I/O interfaces. Logical cores use channels to exchange data within a tile or across tiles. The tiles are connected via an integrated switch network, which uses a proprietary physical layer protocol, and which can also be used to add additional resources to a design. The I/O pins are driven using intelligent ports that can serialize data, interpret strobe signals and wait for scheduled times or events, making the device ideal for real-time control applications. The device can be configured using a set of software components that are rapidly customized and composed. XMOS provides source code libraries for many standard components. The device can be programmed using high-level languages such as C/C++ and XMOS-originated extensions to C, called XC, that simplify the control over concurrency, I/O and time. The XMOS toolchain includes compilers, a simulator, debugger and static timing analyzer. The combination of real-time software, a compiler and timing analyzer enables the programmer to close timings on components of the design without a detailed understanding of the hardware characteristics. 5.1 Logical cores, Synchronizers and Locks Each xCORE Tile has up to eight active logical cores, which issue instructions down a shared four-stage pipeline. Instructions from the active cores are issued round-robin. If up to four logical cores are active, each core is allocated a quarter of the processing cycles. If more than four logical cores are active, each core is allocated at least 1/n cycles (for n cores). Figure 1 shows the guaranteed core performance depending on the number of cores used. Figure 1: Core performance Speed Grade 400 MHz Minimum MIPS per core (for n cores) 1 2 3 4 5 6 7 8 100 100 100 100 80 67 57 50 There is no way that the performance of a logical core can be reduced below these predicted levels. Because cores may be delayed on I/O, however, their unused processing cycles can be taken by other cores. This means that for more than four logical cores, the performance of each core is often higher than the predicted minimum. 5.2 Channel Ends, Links and Switch Logical cores communicate using point-to-point connections formed between two channel ends. Between tiles, channel communications are implemented over X1087, XS1-G04B-FB144 Datasheet 9 xConnect Links and routed through switches. The links operate in either 2bit/direction or 5bit/direction mode, depending on the amount of bandwidth required. Circuit switched, streaming and packet switched data can both be supported efficiently. Streams provide the fastest possible data rates between xCORE Tiles (up to 250 MBit/s), but each stream requires a single link to be reserved between switches on two tiles. All packet communications can be multiplexed onto a single link. A total of eight 5bit links are available between every pair of cores. Information on the supported routing topologies that can be used to connect multiple devices together can be found in the XS1-G Link Performance and Design Guide, X7561. 5.3 Ports and Clock Blocks Ports provide an interface between the logical cores and I/O pins. All pins of a port provide either output or input. Signals in different directions cannot be mapped onto the same port. The operation of each port is synchronized to a clock block. A clock block can be connected to an external clock input, or it can be run from the divided reference clock. A clock block can also output its signal to a pin. On reset, each port is connected to clock block 0, which runs from the xCORE Tile reference clock. The ports and links are multiplexed, allowing the pins to be configured for use by ports of different widths or links. If an xConnect Link is enabled, the pins of the underlying ports are disabled. If a port is enabled, it overrules ports with higher widths that share the same pins. The pins on the wider port that are not shared remain available for use when the narrower port is enabled. Ports always operate at their specified width, even if they share pins with another port. 5.4 Timers Timers are 32-bit counters that are relative to the xCORE Tile reference clock. A timer is defined to tick every 10 ns. This value is derived from the reference clock, which is configured to tick at 100 MHz by default. 5.5 PLL The PLL is used to generate all on-chip clocks. SS_CLK is the reference clock input. It should be supplied with a clock with monotonic rising edges and should be stable before SS_RESET is taken high. Many standard clock frequencies can be used with appropriate settings configured into the PLL. At boot time, before the PLL can be reconfigured, the PLL multiplier is set using the pins specified in the table in Figure 2. The PLL increases the clock frequency to the tile frequency used to run the processor data path and the switch. Further details on configuring the clock can be found in the XS1-G Clock Frequency Control document, X3221.
