ASIC Design


Part I
1、用cmosZ=!( (A&B)| C | D )
2 To implement any combinational logic, what is the minimum set of logic gate? Why there are so many types of standard cells in the library?
3What is Register file, one port embedded RAM, two port embedded RAM?
4Explain how current STA tools calculate the delay using .lib (including cell delay and wire delay)
5Write a sequence of 3-bit grey code. Can you derive a general equation to convert binary to grey code?
6Show the IEEE754 binary representation for the floating-point number (10.5)10 in single precision.
7A,B,C8bit integerZ=A*BZ=A*B+C,比较这两个设计的delay differencein unit of gate(如:the difference is 4 Full Adder + 1 MUXs
8、怎样将一个single-bit信号从快时钟域送到慢时钟域,或慢送到快?Multi-bit信号呢?
9Suppose we have a pipeline which will process the data in 3 cycles. Sometimes the source may have no data to send out, and sometimes the sink may not be able to receive data. Define the interface signals first, and then design the internal control logic. We must keep the throughput 1 data/cycle, and if there are any possibilities the source shall always be able to send out its data.)
10、设计一个计算连续Leading Zeros个数的电路。输入8-bit,输出4-bit
00001000
0100

00100010
0010

10001000
0000

可以parameterize你的设计吗?其hardware是什么样子的?
11Design a round-robin arbiter(轮换仲裁) that can accept 8 requests and give grant signals in one cycle.
12Setup/Hold time,计算电路最大最小延迟

Part II
关于视频的4道题,基础概念
video/image compression 的原理,过程?
H.264 encoding 框图

Part III
几道Cperl编程
