關(guān)于FPGA流水線設(shè)計的論文\r\nThis work investigates the use of very deep pipelines for\r\nimplementing circuits in FPGAs, where each pipeline\r\nstage is limited to a single FPGA logic element (LE). The\r\narchitecture and VHDL design of a parameterized integer\r\na
The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in the Virtex-4 FPGA. Each MGT has its own pattern checker, but bothMGTs in a channel share the same pattern generator. Each channel can load a differentpattern. The MGT serial rate depends on the reference clock frequency and the internal PMAdivider settings. The reference design can be scaled anywhere from one channel (two MGTs)to twelve channels (twenty-four MGTs).
AR0231AT7C00XUEA0-DRBR（RGB濾光）安森美半導(dǎo)體推出采用突破性減少LED閃爍 (LFM)技術(shù)的新的230萬像素CMOS圖像傳感器樣品AR0231AT，為汽車先進駕駛輔助系統(tǒng)(ADAS)應(yīng)用確立了一個新基準(zhǔn)。新器件能捕獲1080p高動態(tài)范圍(HDR)視頻，還具備支持汽車安全完整性等級B(ASIL B)的特性。LFM技術(shù)(專利申請中)消除交通信號燈和汽車LED照明的高頻LED閃爍，令交通信號閱讀算法能于所有光照條件下工作。AR0231AT具有1/2.7英寸(6.82 mm)光學(xué)格式和1928(水平) x 1208(垂直)有源像素陣列。它采用最新的3.0微米背照式(BSI)像素及安森美半導(dǎo)體的DR-Pix?技術(shù)，提供雙轉(zhuǎn)換增益以在所有光照條件下提升性能。它以線性、HDR或LFM模式捕獲圖像，并提供模式間的幀到幀情境切換。 AR0231AT提供達4重曝光的HDR，以出色的噪聲性能捕獲超過120dB的動態(tài)范圍。AR0231AT能同步支持多個攝相機，以易于在汽車應(yīng)用中實現(xiàn)多個傳感器節(jié)點，和通過一個簡單的雙線串行接口實現(xiàn)用戶可編程性。它還有多個數(shù)據(jù)接口，包括MIPI(移動產(chǎn)業(yè)處理器接口)、并行和HiSPi(高速串行像素接口)。其它關(guān)鍵特性還包括可選自動化或用戶控制的黑電平控制，支持?jǐn)U頻時鐘輸入和提供多色濾波陣列選擇。封裝和現(xiàn)狀：AR0231AT采用11 mm x 10 mm iBGA-121封裝，現(xiàn)提供工程樣品。工作溫度范圍為-40℃至105℃(環(huán)境溫度)，將完全通過AEC-Q100認(rèn)證。
