chapter 1: stratix iii device family overview 1?11 architecture features ? march 2010 altera corporation stratix iii device handbook, volume 1 stratix iii devices support configuration data decompression, which saves configuration memory space and time. this feature allows you to store compressed configuration data in configuration devices or other memory and transmit this compressed bitstream to stratix iii devices. during configuration, the stratix iii device decompresses the bitstream in real time and programs its sram cells. stratix iii devices support decompression in the fpp when using a max ii device/microprocessor plus flash, fast as, and ps configuration schemes. the stratix iii decompression feature is not available in the fpp when using the enhanced configuration device and jtag configuration schemes. f for more information, refer to the configuring stratix iii devices chapter. remote system upgrades stratix iii devices feature remote system upgrade capability, allowing error-free deployment of system upgrades from a remote location securely and reliably. soft logic (either the nios embedded processor or user logic) implemented in a stratix iii device can download a new configuration image from a remote location, store it in configuration memory, and direct the dedicated remote system upgrade circuitry to initiate a reconfiguration cycle. the dedicated circuitry performs error detection during and after the configuration process, and can recover from an error condition by reverting back to a safe configuration image, and provides error status information. this dedicated remote system upgrade circuitry is unique to stratix series fpgas and helps to avoid system downtime. f for more information, refer to the remote system upgrades with stratix iii devices chapter. ieee 1149.1 (jtag) boundary-scan testing stratix iii devices support the jtag ieee std. 1149.1 specification. the boundary-scan test (bst) architecture offers the capability to test pin connections without using physical test probes and capture functional data while a device is operating normally. boundary-scan cells in the stratix iii device can force signals onto pins or capture data from pin or logic array signals. forced test data is serially shifted into the boundary-scan cells. captured data is serially shifted out and externally compared to expected results. in addition to bst, you can use the ieee std. 1149.1 controller for stratix iii device in-circuit reconfiguration (icr). f for more information, refer to the ieee 1149.1 (jtag) boundary scan testing in stratix iii devices chapter. design security stratix iii devices are high-density, high-performance fpgas with support for 256-bit volatile and non-volatile security keys to protect designs against copying, reverse engineering, and tampering. stratix iii devices have the ability to decrypt a configuration bitstream using the advanced encryption standard (aes) algorithm, an industry standard encryption algorithm that is fips-197 certified and requires a 256-bit security key.
1?12 chapter 1: stratix iii device family overview architecture features stratix iii device handbook, volume 1 ? march 2010 altera corporation the design security feature is available when configuring stratix iii fpgas using the fast passive parallel (fpp) configuration mode with an external host (such as a max ii device or microprocessor), or when using fast active serial (as) or passive serial (ps) configuration schemes. f for more information about the design security feature, refer to the design security in stratix iii devices chapter. seu mitigation stratix iii devices have built-in error detection circuitry to detect data corruption due to soft errors in the configuration random-access memory (cram) cells. this feature allows all cram contents to be read and verified continuously during user mode operation to match a configuration-computed crc value. the enhanced crc circuit and frame-based configuration architecture allows detection and location of multiple, single, and adjacent bit errors which, in conjunction with a soft circuit supplied as a reference design, allows don?t-care soft errors in the cram to be ignored during device operation. this provides a steep decrease in the effective soft error rate, increasing system reliability. on-chip memory block seu mitigation is also offered using the ninth bit and a configurable megafunction in the quartus ii software for mlab and m9k blocks while the m144k memory blocks have built-in error correction code (ecc) circuitry. f for more information about the dedicated error detection circuitry, refer to the seu mitigation in stratix iii devices chapter. programmable power stratix iii delivers programmable power, the only fpga with user programmable power options balancing today?s power and performance requirements. stratix iii devices utilize the most advanced power-saving techniques, including a variety of process, circuit, and architecture optimizations and innovations. in addition, user controllable power reduction techniques provide an optimal balance of performance and power reduction specific for each design configured into the stratix iii fpga. the quartus ii software (starting from version 6.1) automatically optimizes designs to meet the performance goals while simultaneously leveraging the programmable power-saving options available in the stratix iii fpga without the need for any changes to the design flow. f for more information about programmable power in stratix iii devices, refer to the following documents: programmable power and temperature sensing diode in stratix iii devices chapter an 437: power optimization in stratix iii fpgas stratix iii programmable power white paper
