From 61f2f0214c5999ea42a368a4fc99f03d8eb28d1e Mon Sep 17 00:00:00 2001 From: jcorgan Date: Mon, 8 Sep 2008 01:00:12 +0000 Subject: Merged r9433:9527 from features/gr-usrp2 into trunk. Adds usrp2 and gr-usrp2 top-level components. Trunk passes distcheck with mb-gcc installed, but currently not without them. The key issue is that when mb-gcc is not installed, the build system skips over the usrp2/firmware directory, and the firmware include files don't get put into the dist tarball. But we can't do the usual DIST_SUBDIRS method as the firmware is a subpackage. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@9528 221aa14e-8319-0410-a670-987f0aec2ac5 --- eth/header_ram.v | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 eth/header_ram.v (limited to 'eth/header_ram.v') diff --git a/eth/header_ram.v b/eth/header_ram.v new file mode 100644 index 000000000..699f16a4f --- /dev/null +++ b/eth/header_ram.v @@ -0,0 +1,24 @@ + +module header_ram + #(parameter REGNUM=0, + parameter WIDTH=32) + (input clk, + input set_stb, + input [7:0] set_addr, + input [31:0] set_data, + + input [3:0] addr, + output [31:0] q + ); + + reg [WIDTH-1:0] mini_ram[0:15]; + wire write_to_ram = (set_stb & (set_addr[7:4]==REGNUM[7:4])); + wire [3:0] ram_addr = write_to_ram ? set_addr[3:0] : addr; + + always @(posedge clk) + if(write_to_ram) + mini_ram[ram_addr] <= set_data; + + assign q = mini_ram[ram_addr]; + +endmodule // header_ram -- cgit v1.2.3
